The Sioux Chief 821-2SMQPK2 is a thin strainer and ring assembly built from cast brass with a decorative matte black finish, sized for a 4.5" square opening. It is designed to fit Sioux Chief 820 Series, 821 Series, and 840 Series drain bodies, making it a direct replacement or upgrade strainer for plumbers and contractors servicing existing rough-in drain assemblies.

This part ships from Sioux Chief packaged 5 EA per pack for distributor and contractor stock.

Why Sioux Chief?

Sioux Chief builds this strainer and ring from a cast brass base for durability as the visible, serviceable component of a rough-in drain assembly, with a matte black decorative finish that holds up to repeated cleaning and foot traffic.

Sioux Chief 821-2SMQPK2 – Frequently Asked Questions

1) Will the Sioux Chief 821-2S strainer fit my existing floor drain body?
It fits Sioux Chief 820 Series, 821 Series, and 840 Series drain bodies. If the drain behind your finish floor or wall is one of those three, the 4.5 inch square strainer and ring drops onto it as a direct replacement with no change to the plumbing connection. On any other brand or series of drain body, it is not a stated fit.
2) What size opening does the Sioux Chief 821-2S strainer and ring cover?
It is a 4.5 inch square strainer and ring, sized to match the 820, 821, and 840 Series drain bodies. Measure the square grate you are pulling out: if it is not 4.5 inches square, you are looking at a different drain body and this ring will not sit correctly.
3) Can I change a shower drain finish without tearing out the drain body?
That is exactly what this part is for. The cast brass strainer and ring is the visible, serviceable piece sitting on top of the rough-in drain; the drain body behind the wall or under the floor keeps the plumbing connection. Swap the 4.5 inch square strainer for a matte black, oil-rubbed bronze, or stainless steel one and the finish changes with no demolition, as long as the body is an 820, 821, or 840 Series.
4) Does this strainer include the drain body, or do I need to buy that separately?
Strainer and ring only. There is no drain body, no clamping collar, and no pipe connection included. It is a finish top for an 820, 821, or 840 Series drain that is already installed. New construction jobs need the matching Sioux Chief drain body ordered separately and the strainer used at finish-out.
5) What finishes does the Sioux Chief 821-2S cast brass strainer come in?
Three finishes: matte black (821-2SMQPK2), oil-rubbed bronze (821-2SRBQPK1), and stainless steel (821-2SSQPK1). All three are the same 4.5 inch square thin strainer and ring on a cast brass base, so you can standardize one drain body across a building and change only the visible finish to match the fixtures in each unit.
6) Does the Sioux Chief 821-2S come as a single strainer or in a multi-pack?
It is packaged 5 EA per pack from Sioux Chief. That suits supply houses and service contractors keeping replacement strainers on the truck, but if you only need one grate for a single repair, plan on the 5-piece pack being the unit of purchase.
7) Is a cast brass strainer worth it over plastic for a commercial or high-traffic drain?
Cast brass is the base material here, chosen for strength and corrosion resistance in the one component of the drain assembly that gets walked on, cleaned, and pried at. For corridor, locker room, or multi-family shower service where strainers get damaged and replaced, the brass body plus a decorative finish holds up to repeated cleaning and foot traffic.
8) Why is this called a thin strainer, and where does that matter?
The low-profile design is what makes it work in flush applications where a thick strainer assembly would sit proud of the finish floor or tile. If your tile setter has already pitched to the drain and you need the grate to come in flush rather than stand above the surface, the thin profile is the reason to pick this one.
