Sioux Chief 821-2S 4.25" 19 GA Stainless Steel Strainer with Screws

The Sioux Chief 821-2S is a 4.25" stainless steel strainer manufactured from 19 GA material, built for durable, corrosion-resistant performance in floor and shower drain assemblies. This strainer ships complete with mounting screws, giving plumbers and contractors a straightforward drop-in replacement for worn or damaged drain tops without sourcing loose hardware separately. Sized to fit standard 4.25" drain body openings, the 821-2S is manufactured in Vietnam and packaged for trade use in cases of 100 EA, making it a practical stocking item for service trucks and supply houses alike.

Key Features

  • Trade Size: 4.25" diameter strainer sized to match standard floor and shower drain body openings for a proper seated fit.
  • 19 Gauge Stainless Steel: Corrosion-resistant 19 GA stainless steel construction stands up to constant moisture, washdown, and foot traffic in commercial and residential drain applications, holding its shape better than lighter-gauge stampings.
  • Includes Mounting Screws: Ships complete with screws for a straightforward, no-guesswork installation or replacement on existing drain bodies, saving a trip back to the truck for fasteners.
  • Replacement-Ready Design: Sized as a direct-fit strainer top for 4.25" drain openings, simplifying repair and retrofit work without swapping the full drain body.
  • Rough-In Trade Part: A behind-the-scenes drain component built for plumbers servicing floor drains, shower drains, and similar rough-in assemblies rather than a decorative finish piece.
  • Case Packaging: Packed 100 EA per case, suited to distributors and contractors stocking replacement strainers in volume.

Sioux Chief 821-2S – Frequently Asked Questions

1) Will the Sioux Chief 821-2S strainer fit my existing floor drain body?
The 821-2S is a 4.25 inch strainer top sized to seat in standard 4.25 inch floor and shower drain body openings. Measure the opening in your existing drain body, not the old strainer's visible face, since worn or deformed strainers read small. If your drain body opening is 4.25 inches, this drops in as a replacement top without pulling or replacing the drain body itself.
2) Can I replace just the strainer top instead of the whole drain, or do I have to cut out the drain body?
Only the top. The 821-2S is sold as a direct-fit strainer top for 4.25 inch drain openings, so a strainer that has rusted, cracked, or lost its screws gets handled by unscrewing the old one and setting this one in place. The drain body, riser, and trap stay where they are. That's the usual repair path on renovation and callback work where the drain itself is sound.
3) Does the 821-2S strainer come with mounting screws or do I need to supply my own?
Screws are included with the 821-2S. It ships complete with the mounting hardware, so you are not matching thread or hunting for fasteners on site when you swap out a corroded strainer top.
4) Is a 19 gauge stainless strainer heavy enough for a commercial kitchen or restroom floor drain?
The 821-2S is 19 gauge stainless steel, which is a structural strainer stamping rather than a light decorative one, and it holds its shape under foot traffic and constant washdown better than thinner stampings. Stainless also resists the corrosion that eats plated or steel strainers in wet drain environments. For commercial kitchen and restroom floor drains it's a normal service-grade replacement top. If your drain sees rolling cart or vehicle loads, you want a cast load-rated grate instead of a stamped strainer.
5) How is the Sioux Chief 821-2S packaged for stocking on a service truck or in a supply house?
It is packed 100 each per case. That suits distributors and service outfits that burn through replacement strainers, but if you only need one or two for a single repair, be aware the trade packaging is a case quantity.
6) Is the 821-2S a finish trim piece or a behind-the-scenes rough-in part?
Rough-in. The 821-2S is a functional drain component for floor drains, shower drains, and similar assemblies, not a decorative finish strainer matched to a faucet or trim suite. If a property manager needs the visible drain cover to match polished chrome or brushed nickel fixtures in a finished bathroom, this isn't that part.
7) What is the Sioux Chief 821-2S part number and where is it made?
The manufacturer part number is 821-2S, a 4.25 inch stainless steel strainer, and it is manufactured in Vietnam. Order by 821-2S to get the strainer plus its screws.
