Sioux Chief 889-AOTM ABS Closet Flange with Stainless Steel Swivel Ring, 3" Hub

The Sioux Chief 889-AOTM is an ABS closet flange built for rough-in toilet installations where pipe alignment is not perfectly centered under the fixture. It features a corrosion-resistant 430 stainless steel swivel ring that allows up to 1-1/2" of offset in any direction, letting the plumber dial in the closet bowl setting over a drain line that may be off-center without cutting or relocating pipe. The flange has a 3" hub for connection to 3" ABS DWV pipe, and the test knockout (TKO) design lets it double as a test tee during rough-in pressure testing before the slab or subfloor is closed up. A full-flow 3" I.D. throat keeps the waterway unrestricted through the fitting, with no internal step-down to catch waste or create a flow restriction at the flange.

Key Features

  • Trade Size: 3" hub for direct connection to 3" ABS DWV drain pipe.
  • Full-Flow Design: 3" I.D. throat provides an unrestricted waterway with no narrowing through the flange body.
  • Swivel Offset Ring: 430 stainless steel swivel ring allows up to 1-1/2" of offset in any direction to correct for off-center closet bowl rough-in.
  • Corrosion Resistance: Stainless steel swivel ring resists corrosion compared to plated steel rings on lower-grade flanges.
  • Test Knockout (TKO): Built-in knockout allows the fitting to be used for pressure testing the drain line during rough-in before fixtures are set.
  • ABS Construction: Molded ABS body for solvent-weld connection into ABS DWV drain-waste-vent systems.

Typical Applications

  • New construction closet bowl rough-in over 3" ABS drain pipe
  • Remodel and bathroom renovation where the existing drain is off-center from the new fixture location
  • Residential and light commercial toilet installations
  • Rough-in pressure testing of the drain line prior to fixture set
  • Replacement of damaged or broken closet flanges in ABS DWV systems

Why Sioux Chief?

Sioux Chief builds the 889-AOTM closet flange with a corrosion-resistant 430 stainless steel swivel ring and a full-flow 3" throat so plumbers get both adjustability and an unrestricted drain path in one fitting. The built-in test knockout gives rough-in crews a practical way to pressure-test the line before the floor closes up, reducing callbacks on new construction and remodel jobs. For contractors setting closet bowls over imperfectly located drain pipe, the 1-1/2" swivel offset range removes the need for custom pipe cutting in the field.

Sioux Chief 889-AOTM – Frequently Asked Questions

1) Will the Sioux Chief 889-AOTM closet flange work if my toilet drain is off-center?
That's exactly what it's built for. The 889-AOTM uses a 430 stainless steel swivel ring that allows up to 1-1/2 inches of offset in any direction, so you can rotate and shift the bolt pattern to line the closet bowl up over a drain that isn't centered under the fixture. No cutting or relocating the drain line.
2) Does the 889-AOTM closet flange glue to ABS or PVC pipe?
The body is molded ABS, so it solvent-welds into ABS DWV systems using ABS cement. If your drain stack is PVC, this is the wrong flange - you'd want a PVC-bodied closet flange instead, since ABS and PVC are not the same cement system.
3) Does the hub fit over the pipe or inside it?
Hub style, meaning the pipe goes inside the fitting. The 889-AOTM accepts 3 inch ABS DWV pipe into a 3 inch hub and is solvent welded. That matters on a repair: you need enough exposed pipe below the floor to take the socket, which an inside-fit (spigot) flange would not require.
4) What is the test knockout on this Sioux Chief flange for?
The TKO lets rough-in crews pressure or water test the drain line before the slab or subfloor closes and before any fixture is set. The knockout holds the test, then gets knocked out when you're ready to set the bowl. It saves installing a separate test tee at the closet riser.
5) Why does the swivel ring material matter on a closet flange?
The ring is the part the closet bolts load against, and it sits in the wettest spot in the bathroom. The 889-AOTM uses 430 stainless steel rather than a plated steel ring, so it resists the corrosion that seizes bolts and eats ring slots over time. On a property with repeat wax ring service calls, that's the difference between loosening a bolt and cutting one off.
6) Can I use the 889-AOTM to replace a broken toilet flange in an existing ABS system?
Yes, replacement of damaged or broken closet flanges in ABS DWV systems is a listed application. The swivel ring also helps on a repair where the old bolt slots no longer line up with the bowl, since you get up to 1-1/2 inches of adjustment without touching the pipe.
7) Does a swivel offset flange restrict drain flow?
Not on this one. The 889-AOTM throat is a full-flow 3 inch I.D. straight through the body, with no internal step-down to catch waste or choke flow at the flange. Some offset flanges narrow the waterway to make room for the offset mechanism; this one does not.
8) How does the Sioux Chief 889-AOTM come packaged for a stocking order?
Case quantity is 20 each, and the flange is made in the United States. Useful if you're standardizing one closet flange across a multi-family or new-construction run rather than buying singles.
9) What is the exact part number for the Sioux Chief 3 inch ABS offset closet flange with a stainless ring?
Sioux Chief model 889-AOTM. The suffix tells you the build: ABS body, offset swivel ring, test knockout, stainless ring, 3 inch hub.
