Zinc die-cast, sturdy metal rail, painted wooden handle for optimal power transmission while working. Good power transmission: The wooden handle allows for effective power transfer to the clamping tool, enabling workpieces to be securely fixed or glued with strong pressure. Durable and scratch-resistant: The clamping jaws made from zinc die-casting are particularly robust. Plastic is applied to the contact surfaces to protect sensitive surfaces from scratches. Recommendation: When gluing and working on visible surfaces, always place a spacer such as a wooden scrap or sturdy cardboard on the contact surfaces. Result: more even pressure and no pressure marks on the workpiece.
