Sioux Chief 521-728 Notched Carrier Bracket, Copper-Plated Steel

The Sioux Chief 521-728 is a notched flush valve stubout carrier bracket built for rough-in support of water pipe serving wall-hung water closets. Formed from 16GA copper-plated steel, this bracket supports the flush valve water pipe at 26-1/2" above the finished floor, giving installers a consistent, code-friendly reference point when roughing in commercial restroom piping behind the wall. The extruded notched design runs the full length of the bracket for added strength and rigidity, and mounting washers are included for a complete installation package. This is a behind-the-wall support component intended for plumbers and contractors setting carrier systems for wall-hung fixtures, not a finished or visible fitting.

Sioux Chief 521-728 – Frequently Asked Questions

1) What is the Sioux Chief 521-728 bracket actually used for in a restroom rough-in?
It's a notched flush valve stubout carrier bracket that holds the flush valve water pipe behind the wall on wall-hung water closet installs. It sets the pipe at 26-1/2 inches above the finished floor, so every stall in a commercial restroom roughs in to the same reference point. It stays behind the finished wall, so it's not a visible trim piece.
2) Is the 521-728 the right part if I'm supporting the closet fixture itself rather than the flush valve pipe?
No. The 521-728 supports the flush valve water pipe stubout only. Carrying the weight of a wall-hung water closet is the job of the fixture carrier itself; this bracket works alongside that carrier to hold the water pipe at a consistent 26-1/2 inch height.
3) Does the Sioux Chief 521-728 carrier bracket come with mounting hardware, or do I need to supply washers?
Washers ship with the bracket. You still provide whatever fasteners your carrier or stud framing requires, but the washers for the pipe support are in the package.
4) Will the 521-728 bracket rust in a wet wall cavity?
The bracket is 16GA steel with a copper-plated finish, which is what gives it corrosion resistance for a concealed, damp wall cavity. It's plated steel, not solid copper or stainless, so it's intended for normal behind-the-wall restroom service rather than continuously submerged or chemically aggressive locations.
5) How many Sioux Chief 521-728 brackets are in a pack?
They're packaged 5 each, so one pack covers five fixture rough-ins. Worth knowing if you're pricing out a multi-stall commercial restroom and need a bracket per wall-hung closet.
6) What makes the notched version of this flush valve bracket different?
The notch is an extruded profile that runs the entire length of the bracket, which stiffens it so it doesn't flex while it carries the flush valve pipe. The configuration is listed as Notched, so that's the form you get on the 521-728.
7) What is the exact part number and manufacturer for this notched carrier bracket?
Sioux Chief, part number 521-728. That is the full manufacturer designation for the notched copper-plated steel flush valve carrier bracket, and it's made in China.
