With the parallel vise, you can securely clamp pipes with a diameter of 3/4" to 2" of all kinds. The consistent parallelism of the jaws ensures that the pipes sit flush, providing slip resistance and an even distribution of clamping pressure. The forged and hardened pipe jaws, made of steel, are robust and durable, positioned below the parallel jaws. An anvil surface is included for alignment and shaping tasks. It features adjustable dual prism guidance. The strong spindle with trapezoidal thread is protected. This parallel vise is designed for slip-resistant and deformation-resistant clamping of pipes of all types in the diameter range of 3/4" to 2".
