All two-piece steel riser clamps for steel pipe, MSS SP‑58 Type 8. Each was new and in stock on Amazon as of Oct 22, 2026, and each scores 7.0 or higher on our spec score.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.com at the time of purchase will apply to the purchase of this product.
How the three compare on our spec score
Seven checks from each maker’s submittal or product page and the Amazon listings, equal weight. The rules and every input are in the method section near the end.
PlumbingPicks spec score out of 10, from the makers’ submittals and product pages, read Oct 22, 2026. It is not a customer rating or a load test of our own.
All three makers list their clamp under the same federal and MSS hanger type, Type 8, and all three hold UL listings for the middle sizes. So the basics match.
The score splits them on what each maker puts in writing (load at 2 inches, torque and temperature limits) and on what you can actually buy on Amazon: how many sizes, which finish, and how the bolts go on.

You hang steel or cast iron risers in a dry mechanical space and want a torque number to tighten to on every size.
Skip it if
The riser sits in a damp spot, or it’s 1/2 in. Look at the Empire stainless clamp or the CADDY EZ‑Riser.
Anvil’s Fig. 261 is its standard two-piece riser clamp, and I’ve used it. Anvil calls it an extension pipe or riser clamp, formerly the Afcon Fig. 400. It scored 8.7, the top score here.
Its submittal sheet has the fullest table of the three. For each size from 3/4 to 24 inches it lists the maximum load, weight, overall length, width and bolt torque. That torque column is why it got a 10 on our torque check. The other two makers’ sheets I read don’t give one.
The loads climb with pipe size. Anvil rates 220 lb at 3/4 and 1 inch, 300 lb at 2 inches, 750 lb at 4 inches, 1,600 lb at 6 inches and 2,500 lb at 8 inches. The 2-inch rating is a 10.
Torque runs from 21 ft-lb on the small sizes to 190 ft-lb at 24 inches. Anvil’s note says bolt torques should follow industry standards, and the table gives the numbers.
The plain finish is rated to 650°F. Anvil also makes it hot-dip galvanized, epoxy coated or painted, at 450°F for galvanized and epoxy. That temperature limit is a 10.
Anvil’s install note matters. The clamp is fitted and bolted below a coupling, hub or welded lugs on steel pipe. It isn’t meant to hang from rods; Anvil points to its Fig. 40 for that. It’s sized for standard steel pipe OD.
Four Anvil sizes are on Amazon, and their part numbers match Anvil’s. The 1‑1/2, 6 and 8 inch photos show this clamp. The 4-inch listing (0500173604) shows a coated clamp in its photo, but its text says plain, 750 lb, 12‑7/8 inches. Check the box when it arrives.
It lost points on finish and hardware. Plain steel is a 5 for damp spots, and the loose bolt and nut are a 7.
My call: in a dry chase or a boiler room, this is the clamp I’d order. Knowing the torque saves guessing on the bigger sizes.

You set small steel risers, 1/2 to 1‑1/2 in., in tight spots where holding a nut with a second wrench is a pain.
Skip it if
You need a torque number for the bolts, or a riser over 16 in.
The 510 EZ‑Riser is nVent CADDY’s quick-closing riser clamp for vertical steel pipe, and I’ve used it. Some Amazon listings still carry the older Erico name. It scored 8.1.
Its point is the hardware. nVent says the clamp comes ready to use, with slotted holes and no loose hardware. The serrated washer heads mean you tighten it with one tool. That’s a 10 on our hardware check.
nVent says the slotted holes simplify assembly, and they come only on sizes up to 12 inches. Larger sizes take standard holes.
The line runs 1/2 to 16 inches in 16 sizes, a 9 on range. It starts smaller than Anvil’s 3/4 inch, but it stops below 24 inches.
nVent lists a static load for each size. It’s 255 lb from 1/2 to 2 inches, 390 lb at 2‑1/2, 810 lb at 4 inches and 1,570 lb at 6 inches. The 2-inch figure is 45 lb under Anvil’s and Empire’s, so it’s an 8.5.
The page says to torque the bolts to the recommended value, but it gives no numbers, a 6. It gives no temperature limit either, another 6.
The finish is electrogalvanized: a thin zinc coat, better than plain steel indoors and below stainless. That’s a 7. Like Anvil, nVent says to fit it below a coupling or shear lug on steel pipe.
Four sizes are on Amazon with nVent part numbers: 1/2, 3/4, 1‑1/4 and 1‑1/2 inch. Their photos show the EZ‑Riser. I left out an Erico 3-inch listing whose photo shows a different clamp.
My call: this is the one for small risers. Dropping the halves on and turning one wrench beats fighting a loose nut behind a pipe.
Best for a damp 6 in. riser

Buy it if
You’re supporting a 6-inch steel riser in a wet or corrosive spot, like a pump room, a parking deck or near a cooling tower.
Skip it if
Your riser isn’t 6 inches. Empire makes the other sizes, but Amazon only carries this one.
Empire Industries’ Fig. 50 is its standard riser clamp, and the 50SS is the T-304 stainless version. I’ve used it. The Amazon listing is the 6-inch size. It scored 7.6.
Empire’s submittal says stainless riser clamps are recommended where the clamp needs protection from a corrosive setting. That’s the reason to buy it, and it’s a 10 on finish.
The Fig. 50 line is the widest of the three, 1/2 to 30 inches, a 10 on range. Empire also makes it in plain steel, electrogalvanized, hot-dip galvanized, plastic coated and 316 stainless, plus sizes for ductile iron pipe.
Empire lists a maximum recommended load per size. It’s 255 lb through 1‑1/2 inches, 300 lb at 2 inches, 810 lb at 4 inches and 1,600 lb at 6 inches. The 2-inch figure is a 10.
The listing matches Empire’s sheet. Its title says 6 inches, 1,600 lb, stainless, Empire Industries. Its bullets say 304 grade. Amazon’s brand field says Penn Tool Co. and its maker field says Empire.
Empire’s sheet also gives the bolt size, overall length and weight. The 6-inch clamp takes 1/2-inch bolts, is 15‑3/8 inches long and weighs 3.72 lb.
It lost points on three checks. Only one size is on Amazon, a 4. The submittal gives no torque values, a 6, and no temperature limit, another 6. The bolt and nut are loose, a 7.
Empire notes the plastic coated version keeps the pipe from touching the clamp, to cut noise and stop electrolysis between them. That one isn’t on Amazon.
My call: for a 6-inch steel riser that sweats or sits in a wet room, stainless is worth it. A plain clamp there rusts long before the pipe does.

Fifteen feet is the most the International Plumbing Code allows between vertical supports on steel pipe. At that spacing, every clamp in the table carries the full riser with room to spare, from 1/2 inch to 12 inches.
The margin is smallest on big pipe. At 12 inches, 15 feet of full pipe weighs about 1,530 lb against 2,700 lb of rating. If one clamp carries more than one floor of pipe, run the checker with the real length.
My call: the clamp is rarely the weak link. What it sits on, and whether the pipe has a coupling or lug to bear on, usually matters more.
How much weight a riser clamp holds
Each maker rates its clamp by pipe size. The ratings are close, with one gap at 1/2 to 2 inches.
Rated loads from Anvil’s Fig. 261 submittal, nVent’s 510 EZ‑Riser page and Empire’s Fig. 50 submittal, read Oct 22, 2026.
The three makers use different words for the number: Anvil says maximum load, nVent says static load and Empire says maximum recommended load. Read each as the most that size should carry.
At 6 inches, Anvil and Empire both rate 1,600 lb and nVent rates 1,570. That answers the question people ask Google most about this size.
From 8 to 12 inches, all three match: 2,500 lb at 8 and 10 inches and 2,700 lb at 12 inches. Anvil’s 24-inch clamp is rated 3,200 lb, the most of any size here.
How far apart riser supports go
The International Plumbing Code sets the most distance allowed between vertical supports, by pipe material. Your local code may differ.

Those are from IPC 2021 Table 308.5. Its footnote says that for sizes 2 inches and smaller, a guide goes midway between required vertical supports on the marked materials, so the pipe can’t move sideways.
A riser clamp at each floor usually covers the spacing in a building with 10-foot floor heights. Taller floors may need a clamp in between, set on a lug or coupling.
Section 308.3 adds a materials rule: hangers have to carry the pipe and what’s in it, and can’t be of a material that causes galvanic action. That rule shapes the copper section below.
How to install a riser clamp
The steps follow Anvil’s and nVent’s install notes. A riser clamp works by bearing on something: the floor or steel under it, and a fitting or lug above it.
1
Pick the size by pipe OD
Steel riser clamps are sized for standard steel pipe OD. Anvil says that has to be considered when the riser is another kind of pipe.
2
Find what the clamp bears on
Anvil and nVent both say to fit the clamp below a coupling, hub, shear lug or welded lug. The fitting is what stops the pipe from sliding down through the clamp.
3
Set the ears on the support
The long ears rest on the floor deck, sleeve or framing steel. Jones Stephens describes the job as moving the pipe’s weight over a wider area of the floor.
4
Bolt the halves together
Close the two halves around the pipe and draw the bolts up evenly on both sides, so the clamp sits square.
5
Torque to the number
Anvil lists 21 ft-lb for its small sizes, 32 for 2 to 3 inches and 46 for 3‑1/2 to 6 inches. For CADDY and Empire, ask the maker for the value.
6
Add guides where required
On plastic and other marked pipe 2 inches and smaller, add a mid-story guide per IPC Table 308.5.
Anvil adds one more point: the Fig. 261 isn’t made for hanging from rods. For a clamp hung on threaded rod, Anvil points to its Fig. 40. Our beam clamp guide covers the rod side of hanging pipe from steel.
My call: snug both bolts in turns, a little on each side, rather than running one tight first. A clamp drawn up on one side sits crooked on the floor.
Copper tube needs a copper-size clamp
Copper tube’s outside diameter is smaller than steel pipe of the same size, and bare steel touching copper is what the code’s galvanic rule warns about.

Steel ODs are from ASME B36.10; copper ODs are from nVent’s copper EZ‑Riser table. At 2 inches, a steel clamp’s opening is a quarter inch bigger than the copper tube, so it won’t grip.
Makers sell a separate line for copper. nVent’s 511 EZ‑Riser for copper tube is copper electroplated, from 1/2 to 4 inches. Its loads are lower: 75 lb at 1/2 and 3/4 inch, 150 lb at 2 inches and 300 lb at 4 inches.
It’s a different product from the steel-pipe clamps, so it isn’t scored here. One Amazon listing for the 2-inch copper clamp says 255 lb; nVent says 150. Go by nVent.
Plain, galvanized or stainless
All three makers sell the same clamp in several finishes. The place the riser runs through decides which one you need.
Finish
Where it fits
Maker notes
Plain carbon steel
Dry chases and mechanical rooms
Anvil: rated to 650°F
Electrogalvanized

Anvil: rated to 450°F
Plastic coated
Noise, vibration, mixed metals
Empire: keeps the pipe off the clamp
304 or 316 stainless
Corrosive or wet spaces
Empire: recommended for corrosive settings
Electrogalvanizing is a thin plated zinc layer. Hot-dip galvanizing dips the part in molten zinc for a thicker coat. Both beat bare steel; stainless beats both where water or chemicals sit on the clamp.
On Amazon, only the plain Anvil, the electrogalvanized CADDY and the 6-inch Empire stainless matched their makers on Oct 22, 2026. For hot-dip galvanized or plastic coated clamps, a supply house is the place to look.
My call: plain steel is fine in a heated, dry building. Anything near a floor drain, a pump or an exterior wall gets galvanized or stainless.
Riser clamps on cast iron and plastic pipe
People search for riser clamps for cast iron and PVC. The makers’ sheets say steel-pipe clamps need care on both.

What to do
Cast iron soil pipe
Anvil: sized for steel pipe OD; see its cast iron soil pipe data

Anvil’s Fig. 261 sheet lists cast iron pipe as a use, but says the clamp is sized for steel pipe OD and points to its catalog’s cast iron data. Measure the soil pipe before you order.
For plastic pipe, the code table is the floor, not the whole story. Plastic expands and contracts more than steel, and pipe makers publish their own support rules. Our cast iron vs PVC guide covers how the two behave in a stack.
Riser clamp vs other pipe clamps
Google’s top question after “what is it” is how a riser clamp differs from a pipe clamp. The short answer is direction.

Our guide
Riser clamp

Bolts around the pipe, ears rest on the floor or steel
A riser clamp carries weight straight down into the floor. Horizontal hangers carry it up into the structure through rods. That’s why Anvil says its riser clamp isn’t meant for hanger rods.
A pipe repair clamp is the one that gets mixed up most. It stops a leak but isn’t a support. Our repair clamp guide covers that job.

Jones Stephens is a real plumbing supply brand, and its clamp may hold up fine. But its page lists no load and no hanger standard, so there’s nothing to score it on against three maker tables.
For the mismatched listings, the issue is the listing, not the clamp. If the brand, part number or photo doesn’t match, I can’t tell you what will arrive.
How to choose in five questions
Question
If yes
If no
Is the riser copper tube?
A copper-size clamp, like nVent’s 511
Next question
Is it wet, outdoors or corrosive?
Stainless (Empire Fig. 50SS at 6 in.) or hot-dip galvanized
Next question
Is it 1/2 to 1‑1/2 in. in a tight spot?
nVent CADDY EZ‑Riser
Next question
Do you want a torque number for each size?
Anvil Fig. 261
Next question
Is the floor-to-floor run over 15 ft?
Add a support between floors
One clamp per floor
My call for most jobs: Anvil Fig. 261 on steel risers 2 inches and up in dry spaces, CADDY EZ‑Riser on the small ones, and stainless wherever the clamp will stay wet.
Anvil Fig. 261 scores 8.7 on our spec score, with a load and torque table for every size from 3/4 to 24 inches. nVent CADDY EZ‑Riser is next at 8.1 for small risers.
What is a riser clamp used for?
It supports a vertical pipe run. It bolts around the pipe below a coupling, hub or lug, and its ears rest on the floor or steel at each level.
How much weight can a riser clamp hold?
It depends on size. Anvil rates 300 lb at 2 inches, 750 lb at 4 inches and 2,500 lb at 8 inches; nVent and Empire are close.
How much weight can a 6 inch riser clamp hold?
Anvil and Empire rate their 6-inch clamps at 1,600 lb. nVent rates its 6-inch EZ‑Riser at 1,570 lb.
What is the difference between a pipe clamp and a riser clamp?
A riser clamp holds vertical pipe and rests on the floor. Pipe clamps and hangers hold horizontal or wall-run pipe from rods, straps or beams.
How far apart do riser clamps go?
The 2021 IPC allows up to 15 feet between vertical supports on steel and cast iron, and 10 feet on copper and plastic. Plastic 2 inches and smaller also needs a mid-story guide.
How do you install a riser clamp?
Close it around the pipe right below a coupling or lug, rest the ears on the floor or steel, and tighten the bolts evenly. Anvil lists torque by size.
Can you use a steel riser clamp on copper pipe?
Not well. Copper tube is smaller than steel pipe of the same size, and the IPC bars hanger materials that cause galvanic action. Use a copper-size clamp.
Can you use a riser clamp on PVC pipe?
Follow the PVC maker’s support guide. The IPC sets 10 feet between vertical supports on PVC, with a mid-story guide on 2 inches and smaller.
Can a riser clamp go on cast iron pipe?
Anvil lists cast iron as a use but sizes its clamp for steel pipe OD. Check the soil pipe’s OD against the clamp before ordering.
Can you hang a riser clamp from threaded rod?
Not the Anvil Fig. 261. Anvil says it isn’t meant for hanger rods and points to its Fig. 40 for that.
What size riser clamp do I need?
The nominal size of the pipe. Steel clamps fit steel pipe OD, so 2-inch steel pipe takes a 2-inch clamp. Copper tube takes a copper-size clamp.
How we picked these
Why trust me
I’m Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711), and I’ve used all three picks. Every spec here comes from Anvil’s, nVent’s and Empire’s own submittals and product pages, read Oct 22, 2026. Where I add advice of my own, it’s labeled as my call.
How I pick
Only two-piece steel riser clamps for steel pipe, MSS SP‑58 Type 8, from makers that publish a load table. Each was new and in stock on Amazon, checked through Amazon’s product data the same day.
The listing has to match the maker’s part number and photo. Where one didn’t, I say so or leave it out.
Each card’s spec score comes from the seven checks below. All three score 7.0 or higher.
