Product Description
Because of its large anvil and spindle faces, the 256.1RL-1 is also useful for measuring the thickness of sheet materials like paper, cardboard, rubber, and plastics. It features a ratchet stop, which allows you to hold the setting while working. This prevents the dial from moving past zero.
