This TriGrip will provide instant, positive lateral stability on almost any kind of work surface, without having to use clamps. The special foam impregnated non-slip skin holds any type of material in place, allowing users to route, sand, drill, carve and paint without clamps. When on flat side, TriGrip holds a work piece 1- 3/6″ above the bench top. When set on an edge, the TriGrip raises the piece a full 3 inches above the bench. TriGrips can also be used as support for non-work projects, such as beneath a computer keyboard.
