Sioux Chief 837-HSD Horizontal Closet Carrier, 4" No-Hub Cast Iron, Double Fixture

It centers on a cast iron fitting with 4" No-Hub connections, rated for a 500 lb. maximum static load, and ships complete with the adjustable faceplate, floor-mounted supports, and coupling hardware needed to set and anchor the carrier before the wall finish goes on. This is a standard-pattern unit intended for plumbers and contractors roughing in commercial or multi-fixture restroom partitions where a horizontal No-Hub carrier assembly is specified.

Key Features

Sioux Chief 837-HSD – Frequently Asked Questions

1) Will the Sioux Chief 837-HSD closet carrier connect to my existing 4 inch cast iron DWV line?
Yes, if that line is 4 inch no-hub. The 837-HSD carrier is built around a cast iron fitting with 4 inch no-hub connections, so it joins directly to standard 4 inch cast iron DWV piping with no-hub couplings and bands. If your stack is hubbed cast iron or PVC, you will need an appropriate transition coupling at the connection.
2) Can one 837-HSD carrier support two water closets?
That is what it is for. The 837-HSD is a double-fixture horizontal carrier, arranged for back-to-back or side-by-side water closet rough-ins, and it is rated for a 500 lb maximum static load. For a single wall-hung bowl you want a single-fixture carrier instead.
3) What comes in the box with the 837-HSD, and what else do I need to buy to rough it in?
The 837-HSD ships as a complete kit: adjustable faceplate with gasket, floor-mounted supports, an adjustable ABS threaded coupling with o-ring, fixture bolts, trim, stud protectors, and a rear anchor. You still supply the no-hub coupling bands for tying into the 4 inch cast iron line, plus any fasteners for anchoring to your floor and framing, and the carrier does not include the bowl or the waste connection gasket for the fixture itself.
4) Is the 837-HSD a horizontal or vertical closet carrier, and which one do I need?
It is a horizontal carrier, meaning the cast iron fitting runs horizontally through the chase and the fixture outlets come off that run. That is the arrangement used when your waste line runs horizontally behind the partition wall, which is the normal case in a commercial restroom with back-to-back stalls. If your waste drops vertically through the chase and the fixtures tie into that stack, a vertical carrier is the correct type instead.
5) Can I adjust the carrier depth after it is set, to match my finished wall thickness?
Some, yes. The 837-HSD includes an adjustable ABS threaded coupling with o-ring that lets you set carrier depth on site during rough-in, and the faceplate is adjustable as well. That is how you dial the fixture face to the finished wall before the board goes on.
6) Does the 837-HSD protect the wall studs where it mounts?
Stud protectors are included in the kit, fitted at the carrier mounting points to guard framing members. The carrier also uses floor-mounted supports and a rear anchor, so the assembly is anchored to the floor and the back of the chase rather than hanging off the studs alone.
7) What is the exact part number to order this Sioux Chief double-fixture horizontal carrier?
Order Sioux Chief model 837-HSD. It is a single-model item, packaged 1 each, 4 inch no-hub cast iron, double fixture.
