With the Rockler Bench Dog Bench Cookie Plus Work Grippers, you can add some height and grip to your bench.
These neoprene topped cookies will not slide on the bench, and then a workpiece placed on top of it for sanding, jigsawing, cutting etc. will add both grip to it from slipping, as well as height to clear the bench from the blade.
Each cookie is 76mm (3") in diameter and 25mm (1") thick. If jigsawing, extra height may be needed from the extra length risers(RK-34671).
For finishing, Cookie Cones are available, each fits to a cookie with the point being the only point touching the workpiece(RK-40607).
