Sioux Chief 837-HS Horizontal Closet Carrier, Cast Iron No-Hub

The Sioux Chief 837-HS Horizontal Closet Carrier is a behind-the-wall rough-in assembly for supporting a wall-hung water closet, built around a 4" No-Hub cast iron fitting connection and rated for a 500 lb. maximum static load. This carrier series is available in Left and Right orientation configurations, letting the installer choose the side that matches the rough-in framing without changing the fitting, hardware, or load rating -- one series covers both conditions on a job. Every orientation ships as a complete kit with a cast iron fitting with 4" No-Hub connections, an adjustable faceplate with gasket, floor-mounted supports, an adjustable ABS threaded coupling with o-ring, fixture bolts, trim, stud protectors, and a rear anchor. It mates directly to 4" No-Hub cast iron drain-waste-vent piping, making it a straightforward fit for commercial and multi-family restroom rough-ins where wall-hung fixtures are specified.

Key Features

  • Trade Size: 4" connection sized for No-Hub cast iron drain-waste-vent piping.
  • Durable Construction: Cast iron fitting body provides a rigid, long-service connection point for the carrier assembly.
  • No-Hub Connection: 4" No-Hub joint allows a standard no-hub coupling to join the carrier fitting to the building drain line.
  • 500 lb. Static Load Rating: Carrier assembly is rated for a 500 lb. maximum static load to support the wall-hung fixture across both orientations.
  • Adjustable Faceplate with Gasket: Faceplate adjusts to the finished wall and seals against the fixture with an integral gasket.
  • Floor-Mounted Supports: Floor supports anchor the carrier assembly to the slab for a stable, code-correct fixture mount.
  • Adjustable ABS Threaded Coupling with O-Ring: ABS coupling threads in and out to fine-tune rough-in depth, sealed with an o-ring.
  • Left and Right Orientation Options: Series is offered in Left and Right configurations to fit either side of the rough-in layout, with identical fitting, hardware, and load rating across both.
  • Complete Rough-In Kit: Includes fixture bolts, trim, stud protectors, and a rear anchor so the carrier assembly ships ready to install.

Why Sioux Chief?

The Sioux Chief horizontal closet carrier series pairs a cast iron No-Hub fitting with a complete set of mounting hardware -- faceplate, floor supports, ABS coupling, bolts, trim, stud protectors, and rear anchor -- so contractors have everything needed to set a wall-hung fixture carrier in one box, in whichever Left or Right orientation the rough-in requires. The 500 lb. static load rating and 4" No-Hub connection make it a dependable choice for behind-the-wall rough-in work on cast iron drain-waste-vent systems, regardless of which orientation the job calls for.

Sioux Chief 837-HSL – Frequently Asked Questions

1) What is the difference between the Sioux Chief 837-HSL and 837-HSR closet carriers?
The two differ only in hand. The 837-HSL is the left configuration and the 837-HSR is the right. Both are horizontal carriers with a 4 inch No-Hub cast iron fitting and the same 500 lb static load rating. Pick the hand based on which side the building drain comes into the carrier fitting at your rough-in.
2) Will the Sioux Chief 837-HS carrier connect to existing 4 inch no-hub cast iron DWV pipe?
Yes. The carrier fitting is cast iron with 4 inch No-Hub connections, so it joins to 4 inch no-hub cast iron drain-waste-vent piping with a standard no-hub coupling and band. That makes it workable on renovations of existing no-hub cast iron systems as well as new rough-ins. It is not a hub-and-spigot or PVC solvent-weld fitting.
3) How much weight will the 837-HS wall-hung toilet carrier hold?
The carrier assembly is rated for a 500 lb maximum static load. That covers the fixture plus occupant load for a typical wall-hung water closet in a commercial or multi-family restroom. If your spec calls for a higher rated load, this is not the carrier for it.
4) What comes in the box with the Sioux Chief 837-HS carrier, and what else do I need to buy?
The kit ships with the cast iron fitting, an adjustable faceplate with gasket, floor-mounted supports, an adjustable ABS threaded coupling with o-ring, fixture bolts, trim, stud protectors, and a rear anchor. One carrier per package. You still supply the no-hub coupling and band to tie the fitting into the building drain, the floor anchors into the slab, the fixture itself, and the closet gasket or waste connection the fixture manufacturer requires.
5) Will this carrier work for a floor-mounted toilet?
No. The 837-HS is a carrier for a wall-hung water closet, where the fixture bolts to the carrier faceplate and the load goes down through the floor supports. A floor-mounted toilet sets on a closet flange instead, so you would order a 4 inch no-hub closet flange or closet bend, not a carrier.
6) Can I adjust the rough-in depth after the wall is finished?
There is adjustment built in. The ABS threaded coupling turns in and out to fine-tune the rough-in depth, and the faceplate adjusts to the finished wall thickness, sealing against the fixture with its integral gasket. That is what lets you set the carrier before the wall board goes up and still land the face flush afterward.
7) Is the Sioux Chief 837-HS a floor-mounted or wall-mounted carrier?
It is a floor-supported, horizontal carrier. Floor-mounted supports anchor the assembly to the slab and a rear anchor ties it back, so the fixture load transfers to the floor rather than the wall framing. It installs behind the wall during rough-in, with the fixture hanging off the faceplate.
8) Is the 837-HS suitable for commercial restroom rough-ins?
That is its intended use. It is built for behind-the-wall rough-in on commercial and multi-family restrooms where wall-hung fixtures are specified, in new construction or in renovations of existing no-hub cast iron DWV. The cast iron fitting body gives a rigid connection point for the assembly.
9) Does the Sioux Chief 837-HS carrier carry a Proposition 65 warning?
It may be subject to a Proposition 65 warning. Refer to Sioux Chief's documentation for the specific warning language. Country of origin is China.
