Giant Rubber Clamping Bands. These giant rubber bands are simple, form-fitting clamps for glueing bindings and fingerboards. Easier set up than with clamps and cauls. Pulling equally from both sides, they help to centre the fingerboard on the neck. One band is all it takes to glue a fingerboard to the neck and they are very strong. A 1lb pack of 5 bands. Each band measures 3/4" wide by 84" long. A Stew Mac Product.
