These modern angled grippers are just like their non-adjustable counterparts, sold here.  Use the adjustable model to account for slight variances in leveling your installation.

Also used as a top-mount with the non-adjustable gripper to provide tension to your panel.  This reduces flexing in the material for a more rigid installation.

Grippers provide 1 5/16" space between the wall and the center of your panel in a 90-degree configuration.  There are 4 sizes available to accommodate the most popular panel thicknesses.

Sold with (3) HD-PS2 panhead installation screws.
