Sioux Chief 521-725 Copper-Plated Carrier Bracket, 16-GA Flush Valve Stubout Support

The Sioux Chief 521-725 is a 16-GA copper-plated carrier bracket built as a flush valve stubout support for wall-hung water closets. This rough-in bracket is designed to support the water pipe feeding the flush valve at 26-1/2" above the floor, giving plumbers a solid, repeatable reference point when roughing in commercial and institutional restroom walls. The extruded bracket body runs the entire length of the part for added strength and rigidity, and mounting washers are included for a complete, ready-to-install package. Sold with 5 EA per package, this bracket is a straightforward behind-the-wall support component for wall-hung closet installations rather than a finish or decorative item.

  • Durable Construction: 16-GA copper-plated construction gives the bracket a corrosion-resistant finish suited for rough-in wall framing applications.

Sioux Chief 521-725 – Frequently Asked Questions

1) What does the Sioux Chief 521-725 carrier bracket actually do in a wall-hung toilet rough-in?
It supports the water supply pipe that feeds the flush valve on a wall-hung water closet, holding the stubout at 26-1/2 inches above the floor. The bracket mounts in the wall framing behind the finished wall, so it gives you a fixed, repeatable height reference when you set the stubout. It is a behind-the-wall rough-in support, not a closet carrier for the fixture itself and not a finish item.
2) Does the Sioux Chief 521-725 bracket come with mounting washers, or do I need extra hardware?
Mounting washers come in the package. That covers the washer side of the install, so the main thing you supply on site is the fasteners into your framing and the stubout pipe itself.
3) Is the Sioux Chief 521-725 strong enough to carry the stubout without flexing in the wall?
The body is 16-gauge steel and the extruded profile runs the full length of the bracket rather than stopping short, which is what gives it its rigidity across the span. That full-length extrusion is the structural detail to look at if you are comparing it against a flat stamped strap.
4) What is the Sioux Chief part number and manufacturer number for this flush valve stubout bracket?
Sioux Chief 521-725, and the manufacturer part number is the same, 521-725. Specify it as the 16-gauge copper-plated carrier bracket for flush valve stubout support when ordering.
5) How many Sioux Chief 521-725 brackets come in a package?
Five each per package. For a contractor roughing in a multi-stall commercial restroom that is one pack per five wall-hung closets, which is why it stocks well for new construction and renovation work.
6) Will a copper-plated steel bracket hold up inside a wall?
The copper plating on the 521-725 is there as a corrosion-resistant finish for concealed rough-in framing conditions. It is a plated steel part intended to be buried in the wall, so it is finished for durability rather than appearance.
