One N Done 400MB is a toilet flange repair kit and toilet wax-ring replacement system for low, damaged or broken toilet flanges. Choose the 400 family when the job needs both a new sealing system and flange-repair capability.
WAX-RING REPLACEMENT + FLANGE REPAIR — Combines the ONLY Self-Adjusting reusable wax-free seal with the One N Done repair ring for low, damaged or broken toilet flanges.
DEEPEST FIT — Handles flange positions from approximately 1/8 inch above the finished floor to 1.5 inches below. Within that range, no stacked seal or separate flange extender is needed.
LOCKING METAL BOLTS + REPAIR RING — The repair ring secures with six flange screws. Extra-long 3.5-inch zinc-plated 1/4-20 toilet bolts lock into the One N Done flange and will never spin freely during installation.
EASIER ALIGNMENT — Lock Nuts hold the bolts upright and help center the seal, flange and toilet. Stainless-steel washers and nuts provide familiar metal hardware.
REUSABLE SEAL + SHIMS — The wax-free seal can be repositioned if the toilet is lifted or reset. Included toilet shims help level and stabilize the bowl when a high flange or uneven tile causes rocking.
Choose 400MB when you need toilet wax-ring replacement plus flange repair and prefer metal mounting bolts.
