The Set-Rite® spacers kit includes all four individual spacers, 1/8, 1/4, 1/2, and 3/4 in. Our Set-Rite® spacers will work for any new installation or repair on an existing toilet flange. If you are remodeling or installing a new floor such as ceramic tile, marble, granite or wood and your flange is below the finished floor level, you can use our spacers with any Set-Rite® toilet flange extension kit. The four individual spacers can be stacked to any height or can be snapped in half to support an existing closet flange.
