For an older Delta two-handle faucet with clear knobs, the Delta H21 is the original clear knob; Delta staff say it normally attaches to the RP1740 stem. For a non-Delta, non-Moen faucet, the Danco 89419 is a single oil-rubbed-bronze lever that comes with adapters and a sizing gauge. Order one handle per side, and match the stem before you match the style.

A replacement faucet handle should match the operating connection first. Finish and appearance come after the actual faucet and mounting details are identified.
Replacement faucet handle choices compared
| Handle | Consider when | Main limitation |
|---|---|---|
| Delta H21 | The exact faucet’s parts documentation specifies H21 | Not a universal Delta handle; confirm package quantity |
| Danco 89419 | The actual stem matches the maker’s supplied fitting system | Maker does not recommend it for Moen or Delta; one handle per package |
| Another OEM handle | A different code is specified for the installed faucet | Similar appearance does not establish stem fit |
These picks solve different fit situations. Do not use the universal kit as an assumed alternative to the Delta pick.
Delta H21: buy it by the faucet’s parts list
Choose Delta H21 when the exact kitchen or bathroom faucet documentation identifies that handle code. The maker page (deltafaucet.com) identifies H21 as a clear knob set, and Delta publishes a 2102-LHP–H21 kitchen faucet configuration (deltafaucet.com) using it.
Skip it for an unidentified stem or another Delta series merely because the old handle is clear plastic. A handle’s outer shape, trim finish or hot/cold button can resemble another model without sharing the same mounting arrangement.
In a Delta staff answer on the H21 page, the knob “would normally attach to a RP1740” stem. The hot and cold indicator buttons (RP18373) and set screws (RP5885) are listed as separate parts. The Amazon.com listing is titled as a single knob kit and matched H21 in its model and part fields, so order two for a two-handle faucet and check the box on arrival.
Danco 89419: a selective adapter-based lever
Choose Danco 89419 only after matching the actual stem to the maker’s intended fitting system. The exact product page (danco.com) describes an oil-rubbed-bronze lever with supplied bushings, spacers, screws and a sizing gauge.
Skip it for Moen or Delta: Danco expressly does not recommend this model for those brands. Universal in the title does not erase that limitation or establish fit on every other faucet.
The maker lists one handle per package. The checked new Amazon.com offer was in stock and matched 89419 in title, model and part fields. If replacing both sides of a faucet, confirm the required quantity and approved orientation for each position rather than treating one package as a pair.
Identify the faucet before counting splines
Record the brand and full faucet model if available. Check the owner’s information, purchase record and manufacturer identification process. An old replacement handle may be an aftermarket part, so its logo or shape is not always reliable evidence of the underlying faucet.
Delta’s parts-identification tool (deltafaucet.com) directs users from the product model to its relevant parts and diagram. Use the diagram for the actual revision rather than treating a general brand list as the final compatibility check.
If the faucet cannot be identified, have a suitable repair supplier or plumber assess the intact parts and mounting details. Keep the handle, correct retaining hardware and any existing adapter together so their relationship is clear.
Stem diameter or spline count can help describe a part, but those measurements alone do not establish the required handle depth, stop arrangement or screw. Resolve the complete match before buying a different style.
Check the mounting interface and retaining hardware
Identify whether the handle uses the specified splined, shaped or adapter-based connection. Include the stem projection above the trim and the handle’s internal depth. A handle that starts onto the stem may still bottom out before it engages correctly.
Match the exact retaining screw and any specified washer, spacer or adapter. A screw with a similar head may have a different thread or length. Do not compensate for an unverified fit with an extra-long screw or an improvised stack of washers.
Inspect the visible condition as appropriate under the faucet instructions. A damaged handle socket and a damaged stem are different repair problems. A new handle cannot establish that worn or broken mounting hardware below it is sound.
Use the maker’s method and permitted tools for removal and assembly. Do not force a seized handle against the faucet body or finish. Seek suitable help when the parts cannot be removed without damage or the required water isolation is uncertain.
Universal adapters still need a verified match
Danco’s 89419 description (danco.com) lists several plastic bushing sizes, spacers and a metal bushing. Those are supplied fitting parts, not permission to combine pieces arbitrarily until the handle seems tight.
Use the exact kit’s current sizing and assembly instructions. Confirm that the intended bushing engages the actual stem and seats as designed. A partly engaged adapter can feel secure before the handle is used through its full permitted movement.
Do not grind a stem, modify a bushing or force an oversized screw to make a universal handle fit. If the supplied system does not produce the specified connection, choose the correct replacement or have the underlying faucet assessed.
Keep any unused adapters labeled with their own kit. A loose plastic insert from an earlier repair may look useful but still have a different size or mounting purpose.
Kitchen, bathroom and tub handles are not one family
Use the faucet’s application and parts code together. A manufacturer may sell visually similar sink and tub handles with different mounting details. Do not assume the brand and finish provide enough information.
Delta’s H25 page (deltafaucet.com), for example, identifies a metal lever set for two-handle bathroom use and distinguishes a corresponding Roman-tub handle in its support answers. That example is not a checked purchase recommendation here.
For related whole-fixture selection, see our bathroom faucet guide and Delta kitchen faucet guide. The installed faucet’s repair parts remain the basis for a handle-only purchase.
Do not use a sink-handle guide to choose shower trim or alter a temperature-control assembly. Identify that valve and its exact trim requirements separately.
Knob-to-lever changes need clearance and movement checks
A lever sweeps through a different space from a round knob. Check the actual faucet spacing, spout, backsplash and nearby objects before choosing it. Include the handle’s required travel and the user’s normal grip.
Confirm the approved hot and cold arrangement and correct indications. Two similar handles may have a specific position or orientation in the faucet design. A kit containing one handle does not establish that the same assembly suits both sides without further checks.
A lever style by itself does not establish accessibility compliance for the completed faucet or installation. Match any applicable requirements to the actual fixture and operating arrangement rather than transferring a claim from a separate handle family.
Check finish names and materials by exact model. Oil-rubbed bronze and clear acrylic are different product choices, and a familiar finish name does not guarantee a visual match to another maker or an aged fixture.
A handle change is not a complete leak diagnosis
Separate a loose or broken grip from water leaking at the spout, around the stem or below the faucet. Those symptoms may need different parts and work. Do not order a cosmetic handle simply because the leak is noticed when it is turned.
Have the faucet assessed using its exact service information. Record where water appears and when it occurs. A handle that turns farther than before or no longer operates normally also needs the underlying cause identified.
Do not keep applying more force to stop a drip. The correct shutoff and repair process depends on the faucet and its condition. A longer lever can apply different force without resolving worn sealing or operating parts.
If the repair requires opening water-containing components, use the appropriate isolation and maker procedure with qualified help where needed. This selection guide does not provide a universal stem or internal-valve repair sequence.
A useful replacement-handle order
- Identify the faucet. Full model and relevant revision or parts diagram.
- Record the handle code. Exact OEM part or confirmed adapter-kit application.
- Match the mounting. Stem form, depth, screw and required spacers.
- Check the travel. Spout, backsplash, grip and correct hot/cold arrangement.
- Confirm the package. One handle, a pair and included hardware are different order details.
- Inspect on delivery. Match marked parts and current instructions before use.
Keep the repair code with the faucet record afterward. That makes a later matching replacement easier than trying to identify a worn knob by appearance again.
Frequently asked questions
Does a universal faucet handle fit every brand?
No. Danco specifically does not recommend the linked 89419 model for Moen or Delta. Match the exact kit and installed stem.
Can I choose a handle by spline count alone?
No. Also verify the stem dimensions, projection, handle depth, retaining hardware and faucet application.
Does one package contain both hot and cold handles?
Check the exact offer. Danco lists one 89419 handle; the checked H21 offer has conflicting individually/pairs wording that needs confirmation.
Will replacing the handle stop a faucet dripping?
Not necessarily. A loose grip and a leaking sealing or operating part are different issues. Use the exact faucet service information.
Can a lever replace a knob just because it fits the stem?
Also confirm the approved travel, orientation, clearance, hardware and faucet application before choosing the change.
How we chose
This document-based guide makes no hands-on testing claim. We read exact maker handle pages and Delta’s identification guidance and example faucet configuration. On October 14, 2026, both linked standard new offers were in stock from Amazon.com and matched model and part numbers. The H21 quantity wording conflicts; confirm delivered contents and the exact faucet’s current parts diagram. Read our selection method and about Plumbing Picks.
