Infinity Drain introduced a new Universal Clamping Ring for use with 4”x4” center drains. The durable ABS Universal Clamping Ring can be installed with the Schluter®-KERDI bonding flange to keep the shower system waterproof warranty intact. The new Universal Clamping Ring will allow designers and installers to specify this popular drain size in any environment ­– to upgrade the look of the drain and to match other luxury fixtures in their bathroom, the company says.
