The Plumb Pak PP835-56 Toilet Anchor Flange solves the cracked flange problem without tearing out concrete. This metal repair flange stops toilet wobble from damaged flanges or uneven floors — and it beats full flange replacement by a country mile.
The anchor flange measures 7-1/8 inches height by 5-1/8 inches width and fits standard 3-inch closet drain openings. Works with round and oval-bottom toilet flanges, which covers about 95% of what’s installed in Montana homes.
Universal Compatibility That Counts
The kit works with standard 1-1/4 inch bolt patterns and fits toilets from Kohler, American Standard, Gerber — basically any major brand. That universality matters when you’re fixing a 20-year-old toilet and can’t remember who made it.
Plumb Pak includes the screws and washers, so there’s no second trip to the hardware store. The metal construction (generally zinc-plated steel) handles Montana’s humidity swings better than plastic repair flanges that crack after a few freeze-thaw cycles.

Real-World Performance
Contractors rate this flange 4.5 stars at Ace Hardware and 4.7 stars at Blain’s Farm & Fleet. Users highlight ease of installation and sturdy metal construction — the two things that matter most on a service call.
The installation process involves removing the old flange, positioning the anchor flange over the opening, securing it with the included screws, then reinstalling the toilet with a new wax ring. Takes about 30 minutes if the subfloor’s solid.
This flange handles residential and light-commercial toilet repairs, plus retrofitting projects where the existing flange is damaged. The metal build ensures long-lasting stability — crucial when you’re guaranteeing the repair.
The Bottom Line
The Plumb Pak anchor flange delivers what matters: universal fit, metal construction, and included hardware. It repairs cracked flanges without replacement and stops wobble from damaged flanges or uneven floors.
Available through regional suppliers like McKay’s Hardware, this flange earns its place in any plumber’s truck. The consistent 4.5+ star ratings across retailers tell the real story — it works.
