German made Klemmsia clamps are still considered the best cam clamp made. These versatile clamps are used for clamping: the bridge to the top, the braces to the top and back, the fingerboard to the neck blank, and the top and back to the sides. These convenient clamps have hundreds of uses in the shop. Made of very light but very rigid hornbeam, they belie their light weight and can exert a force of 330lbs. when the cam is fully pulled. The bar is zinc-plated spring steel to prevent rust and ensure smooth sliding. Each jaw has a cork pad attached to prevent marring. Three sizes.
