Sioux Chief 886-R Flange Extension Ring, 1/2" Thick

Sioux Chief 886-R Flange Extension Ring, 1/2" Thick

The Sioux Chief 886-R Flange Extension Ring is a 1/2" thick 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. It installs between the existing closet flange and the finished floor to close the gap created by an added floor buildup, such as extra underlayment, a mortar bed, or a second layer of flooring poured or set after the flange was originally installed. Manufactured in the United States, this extension ring ships 20 per case, making it easy for plumbing contractors and wholesale counters to keep working stock on hand for renovation calls, tile jobs, and new-construction punch-list items. Because it is purpose-built for closet flange applications, it is sized to seat cleanly under the flange body without disrupting the drain connection or waste line below, giving the installer a quick, single-piece fix instead of a full flange replacement.

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 is manufactured in the United States to support dependable closet flange installations. Keeping a case of these extension rings 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.
