Set-Rite - Toilet Flange Extender Kit (1/4" to 3/8")
The Only Code Approved Toilet Flange Extender and Spacer System which will work for any new installation or repair of an existing toilet flange.  Our Extender & Spacers measure 7-1/4" in diameter, just slightly larger than a 7" flange. If you are remodeling and are installing a new floor such as: ceramic tile, marble, granite or wood You can use our Extender kits to go on Top of your existing flange if it is below the finished floor level. You can use our Spacers to go underneath your flange which is designed to snap-in-half and will slide under your raised toilet flange and support your toilet holddown bolts. Then just install your flooring up to the already secured flange. There is a video on YouTube with installation instructions. When using our Extender Kits you may choose either the gasket supplied with each kit or a standard wax ring without rubber cones. **Code Approved by IAPMO (International Association of Plumbing and Mechanical Officials)
