Set-Rite - Original Toilet Flange Extender Kit (1/4" to 1-5/8)
This is the only Code Approved Extender and Spacer System which will work for any possible installation or repair of a toilet flange. Our Extender & Spacers measure 7-1/4" in diameter, just slightly larger than a 7" flange.   When you have an existing toilet flange and are adding a different flooring such as: ceramic tile or marble, each size of out spacers has a 'snap-in-half' groove which slides underneath the flange and will support the johnny bolts. If you go to our website or YouTube you will see a demonstration video that explains how to install a new toilet flange and also use our Extender Kit with either the gasket supplied with each kit or a wax ring.
