Sioux Chief 837-PHS 4" PVC Horizontal Closet Carrier, 500 lb

The Sioux Chief 837-PHS is a horizontal closet carrier built around a 4" Schedule 40 PVC spigot fitting, engineered for behind-the-wall rough-in support of a wall-hung water closet. The lightweight PVC waste fitting reduces overall assembly weight versus traditional cast-iron carriers, simplifying shipping, handling, prefab, and on-site installation for plumbing contractors. This carrier is available in Left-Hand and Right-Hand connection configurations to match either rough-in layout, and both versions carry the same 500 lb. maximum static load rating and ship complete with everything needed for a code-compliant rough-in installation.

Key Features

  • Trade Size: 4" Schedule 40 spigot connections for direct joining to 4" PVC waste and vent piping.
  • Durable Construction: PVC waste fitting is corrosion resistant and impervious to sewer gases, standing up to long-term exposure behind the wall without the weight penalty of iron.
  • Configuration: Horizontal carrier design for wall-hung fixture installations where the waste connection runs horizontally into the carrier assembly, available in Left-Hand or Right-Hand connection orientation to suit either rough-in layout.
  • Load Rating: Rated for a 500 lb. maximum static load, supporting the wall-hung water closet and typical occupant loading on either hand configuration.
  • Complete Kit: Includes the 4" PVC fitting, adjustable faceplate with gasket, floor-mounted supports, ABS coupling with integral gasket, fixture bolts, trim, and stud protectors - everything needed in one box for the carrier installation.
  • Adjustable Faceplate: Faceplate with gasket adjusts to accommodate wall thickness and fixture positioning during rough-in.
  • Stud Protectors: Included stud protectors guard framing members at the carrier mounting points.

Why Sioux Chief?

Sioux Chief builds this closet carrier around a corrosion-resistant 4" PVC waste fitting that stands up to sewer gas exposure while keeping the complete assembly lighter and easier to prefab than iron carriers. With the faceplate, floor supports, coupling, bolts, trim, and stud protectors included in one kit, plumbing contractors get a complete 500 lb.-rated horizontal carrier solution for wall-hung fixture rough-in, available in Left-Hand or Right-Hand connection configurations, without sourcing separate components. Whether the rough-in calls for a Left-Hand or Right-Hand waste connection, the 837-PHS delivers the same durable PVC construction, the same 500 lb. load rating, and the same complete-kit convenience, giving plumbing contractors one reliable part number to stock for either orientation on the job site.

Sioux Chief 837-PHSL – Frequently Asked Questions

1) Do I need the left-hand or right-hand Sioux Chief 837-PH closet carrier?
The 837-PH horizontal carrier is built in two hands: 837-PHSL is left-hand and 837-PHSR is right-hand. Hand refers to the side the horizontal waste run enters the carrier as you face the wall from the fixture side, so pick based on which direction your 4 inch waste line comes in. Order the wrong hand and the spigot will point away from your rough-in.
2) Will the Sioux Chief 837-PH carrier connect straight to 4 inch PVC DWV pipe?
Yes. The waste fitting is 4 inch Schedule 40 PVC with spigot connections, so it joins directly into 4 inch PVC waste and vent piping with standard solvent-weld hubs or couplings. The kit also includes an ABS coupling with an integral gasket for the fixture-side connection.
3) What comes in the box with the Sioux Chief 837-PH carrier, and what do I still have to buy?
The kit ships with the 4 inch PVC fitting, the adjustable faceplate and gasket, floor-mounted supports, an ABS coupling with integral gasket, fixture bolts, trim, and stud protectors. What is not in the box is the water closet itself, the waste and vent pipe, solvent cement, and the framing or blocking in the wall.
4) Can the 837-PH carrier faceplate be adjusted for different wall thicknesses?
Yes. The faceplate is adjustable and comes with its gasket, so you can set it to the finished wall thickness and dial in fixture position during rough-in rather than being locked to one depth.
5) Is the Sioux Chief 837-PH a horizontal or vertical closet carrier?
Horizontal. The 837-PH is set up for installations where the waste connection runs horizontally into the carrier assembly. If your 4 inch waste drops vertically behind the fixture wall, a horizontal carrier is the wrong configuration for that rough-in.
6) Is the Sioux Chief 837-PH carrier suitable for a commercial restroom or only residential?
Both. It is used for wall-hung water closet rough-in in commercial restroom construction, residential and multi-family bathrooms, and new construction or renovation behind-the-wall work in framed walls. The limit on the commercial side is the 500 lb static load rating, not the application.
7) Does the 837-PH protect the wall studs where it mounts?
Stud protectors are included and go at the carrier mounting points to guard the framing members. The carrier also lands on floor-mounted supports rather than hanging off the studs alone.
