Prevents toilet breaking off the wall & possible injury. Wall-hung china toilet bowls are only rated to support up to 300 lbs. With the toilet support, you can now increase the weight capacity of a wall-mounted toilet to 1, 000 lbs. The support installs in minutes under most wall-mounted toilets, providing additional vertical support. The toilet support helps maintain the ability to clean the floor under wall-mounted fixtures with a specially engineered, extra-wide leg base which can be raised up to 4" off the floor for cleaning access. The toilet support is made from high impact ABS with the carriage & foot made from chemical & stain resistant flexible PVC that forms to the contour of the toilet. The adjustment threaded rod is made from plated steel. Adjusts from a minimum of 210mm to a maximum of 330mm. Code: D4598
