Toilet flange repair
Fix-A-Flange
Fix a broken toilet flange without replacing it. The steel horseshoe goes under or over the broken bolt slot and screws to the floor, so the toilet bolt holds again.
Cast iron, plastic, copper or brass flanges
No cutting out the flange
PSF-100 single
PSF-100-2KIT kit
Stop the rock
A broken bolt slot can’t hold a toilet. Fix-A-Flange gives the bolt something solid to hold, to stop wobbly and leaky toilets without tearing out the flange.
Center slot
The toilet bolt goes through here
Screw slots
Fasten it to the floor on each side of the bolt
Curved to fit
Follows the flange, under or on top
No tear-out
Keep the flange. Repair the broken slot instead of cutting out and replacing the closet flange.

Flange materials: cast iron, plastic, copper and brass.
Under or over
Under the broken flange is recommended when you can get it there. If you can’t, set it on top and shim the toilet if it doesn’t sit flat.
Wood or concrete
Fix-A-Flange Complete (PSF-100-2KIT) includes 4 screws for wood or concrete floors. With the PSF-100 single, use screws made for your floor.
Single or kit
PSF-100: one horseshoe for one broken slot.
PSF-100-2KIT: Fix-A-Flange Complete, two horseshoes and the hardware for both sides.
Which one do I need?
The PSF-100 single horseshoe, or the PSF-100-2KIT Fix-A-Flange Complete with two horseshoes and the hardware.
PSF-100
Fix-A-Flange, single
One steel horseshoe for one broken bolt slot. Screws and toilet bolts not included.
PSF-100-2KIT
Fix-A-Flange Complete
Everything for both sides: 2 horseshoes, 4 wood or concrete screws, 2 toilet bolts with nuts, 2 washers and 2 plastic locking washers.
Under or over
Slide it under the flange when you can. When you can’t, set it on top.
Under the flange
Recommended if possible. Remove the flange screws, slide the horseshoes under the broken flange and screw them down.
On top of the flange
Set the horseshoes on the flange and screw them down. Check the toilet still sits flat. If it doesn’t, shim the toilet (shims sold separately).

Six steps
1
Pull the toilet
Shut off the water, flush, empty the bowl and tank, disconnect the supply and unbolt the toilet.
2
Bolt the horseshoe
Put a toilet bolt through the center hole and lock it with a plastic locking washer.
3
Place the horseshoe
Under: remove the flange screws and slide the horseshoe under the broken flange. Over: set it on top.
4
Line up the bolts
Keep the bolts centered on the flange and square to the wall.
5
Screw it down
Drill 3/16″ holes through the flange into the floor if needed, then screw the horseshoe to the floor.
6
Reset the toilet
Install a new toilet seal, reset and secure the toilet, turn the water on and flush to check for leaks.
Going on top? Measure the horseshoe height against the recess under the toilet first. If the horseshoe sits higher, shim the toilet.
Resetting the toilet?
Skip the wax.
Every reset needs a new toilet seal. Fernco Wax-Free Toilet Seals stick to the toilet and seal inside the drain pipe. No scraping, no mess, and floors up to ¾″ above the flange are covered.
- Seals in the pipe, not on the flange
- Reset the same toilet with the same seal
- Made in USA

Common questions
PSF-100 or PSF-100-2KIT?
One broken slot and your own screws and bolts? The PSF-100 single horseshoe. Both sides, or want everything in one box? The PSF-100-2KIT Fix-A-Flange Complete has two horseshoes, 4 wood or concrete screws, 2 toilet bolts with nuts and the washers.
Should it go under or over the flange?
Under the flange if you can. Remove the flange screws and slide it under. If it won’t go under, set it on top and check that the toilet still sits flat.
Will it work on a concrete floor?
Yes. Fix-A-Flange Complete (PSF-100-2KIT) includes screws for wood or concrete. With the PSF-100 single, use screws made for your floor.
The toilet rocks after I put it on top. Now what?
The horseshoe is sitting higher than the recess under the toilet. Shim the toilet between its base and the floor, or move the horseshoe under the flange.
Do I need a new toilet seal?
Yes. Install a new seal whenever the toilet comes up. A Fernco Wax-Free Toilet Seal is one option.
