Gyford WS Series Adjustable Surface Mount Panel Grippers
Use these adjustable surface mount grippers to help level panels on uneven surfaces.
These are also used as a top mount with the non-adjustable variant as a top and bottom mount combination. By using these parts together, you are able to tension a panel, reducing flex in the material and providing a more stable mount.
These grippers provide 2 3/4" - 3 1/2" space between the mounting surface and the bottom of your panel.
