Set-Rite Floor Spacers
July 1, 2005

Set-Rite spacers install underneath new or existing toilet flanges. This unique design allows plumbers to set toilet flanges to the finished floor height during the rough-in and prior to the installation of any flooring. The Set-Rite system offers various spacer thicknesses, which are stackable and adjust to any finished floor height.
