Adjustable Bench Support Bolt Requirements

The Adjustable Rectangular Bench (BB-ADJR-60 and BB-R26-ADJR) is designed for use in pre-tiled and post-tiled application over UBC approved tile backing systems. 

  • BB-R26-ADJR adjusts from 19" to 32" 
  • BB-ADJR-60 adjusts from 33.5" to 60" wide 

Both Adjustable Rectangular Benches are suitable for mounting directly to the face of tile substrate (ultimate method), or after finish tile is installed. Wood blocking is not required unless Support Bolts are being used in the installation.

If the unit is expanded beyond 36″ AND/OR an open-ended installation is being considered, BT-17 OR Support Bolts are required!

Using the Support Bolt system allows for a “floating” bench look.
