Sioux Chief 886-R Closet Flange Extension Ring, Multi-Thickness

The Sioux Chief 886-R Closet Flange Extension Ring is a spacer built for rough-in plumbers who need to raise the working height of a closet flange without tearing out and replacing the entire flange assembly. This extension ring family is available in 1/4" Thick and 1/2" Thick options, letting the installer match the exact gap created by an added floor buildup — extra underlayment, a mortar bed, or a second layer of flooring poured or set after the flange was originally installed. It installs between the existing closet flange and the finished floor to close that gap in a single piece, instead of requiring a full flange replacement. Manufactured in the United States, the 886-R ships 20 per case, making it easy for plumbing contractors and wholesale counters to keep working stock of both thicknesses on hand for renovation calls, tile jobs, and new-construction punch-list items. Because it is purpose-built for closet flange applications, each extension ring is sized to seat cleanly under the flange body without disrupting the drain connection or waste line below, giving the installer a quick fix for the specific buildup height encountered on site. Whether the job calls for the 1/4" Thick ring or the 1/2" Thick ring, both are part of the same 886-R family and ship from the same case pack, so crews can stock the full thickness range from a single family of parts rather than ordering separate flange replacements for every buildup height they encounter.

Key Features

  • Thickness Options: Available in 1/4" Thick and 1/2" Thick versions to match the exact floor buildup on the job.
  • Purpose-Built Design: Made specifically to extend closet flange height whenever added flooring leaves the existing flange sitting too low relative to the finished floor.
  • Time-Saving Repair: Lets a plumber correct a low flange on site without cutting out and re-setting the entire closet flange.
  • Single-Piece Fix: Seats cleanly under the flange body without disrupting the drain connection or waste line below.
  • Country of Origin: Manufactured in the United States.
  • Packaging: Sold 20 per case, sized for rough-in truck stock and wholesale counter inventory.

Why Sioux Chief?

Sioux Chief is a name plumbing contractors rely on for rough-in and behind-the-wall components, and the 886-R extension ring family is manufactured in the United States to support dependable closet flange installations. Keeping a case of both the 1/4" and 1/2" thicknesses on the truck lets plumbers resolve a low flange on the spot instead of scheduling a return trip once floor height changes mid-job, helping crews stay on schedule during both new construction and remodel work. For distributors and contractors who already stock Sioux Chief closet flanges and drainage products, the 886-R is a natural companion item to keep alongside that core rough-in inventory, covering a range of buildup heights from a single family of extension rings sold 20 per case.

Sioux Chief 886-RQ – Frequently Asked Questions

1) My toilet flange ended up too low after new tile went in. Will a Sioux Chief 886-R extension ring fix it without replacing the flange?
That is exactly what the 886-R is built for. It is a 1/2 inch thick spacer that sits between the existing closet flange and the finished floor, closing the gap created by added floor buildup such as extra underlayment, a mortar bed, or a second layer of flooring set after the flange went in. It seats under the flange body without disturbing the drain connection or waste line below, so you correct a low flange on site instead of cutting out and re-setting the whole assembly.
2) How much height does a Sioux Chief 886 extension ring add, and is there a thinner option?
Two thicknesses are offered: the 886-R adds 1/2 inch, and the 886-RQ adds 1/4 inch. Pick based on how much buildup went over the subfloor. A single layer of thinset and tile usually lands closer to the 1/4 inch ring, while a mortar bed or a second layer of flooring is where the 1/2 inch ring comes in. They are single-piece rings, so stacking is a judgment call for the installer, not a rated application.
3) Should I use a flange extension ring or just replace the closet flange?
An extension ring is the move when the flange itself is sound and only the height is wrong, which is the usual outcome when floor height changes mid-job. The 886-R raises the working height in one piece, with no cutting into the waste line. Replace the flange instead if it is cracked, the bolt slots are broken out, or the drain connection below is compromised, since a ring only addresses elevation and not a damaged flange body.
4) What is the part number for the 1/4 inch Sioux Chief closet flange spacer?
The 1/4 inch version is Sioux Chief 886-RQ. The 1/2 inch version is 886-R. Both are closet flange extension rings in the same 886 family, differing only in thickness.
5) Does installing an 886-R extension ring change the toilet rough-in or waste line below?
No. The ring is sized to seat cleanly under the flange body without disrupting the drain connection or the waste line, so the rough-in centerline stays where it is. All it changes is the elevation of the flange face relative to the finished floor, which is what sets your wax ring or seal height.
6) How are Sioux Chief 886-R extension rings packaged for truck stock?
They ship 20 each per case, which is sized for rough-in truck stock and wholesale counter inventory. For a service plumber that means one case covers a lot of remodel and punch-list calls where the flange comes up low after flooring. The rings are manufactured in the United States.
