Available in two sizes, 4-1/2 inches (XF-45) and 5 inches (XF-50), the RIDGID Quick-Acting Vises feature both forged steel construction and a quick-action mechanism. Other features include the patented jaw alignment system, which enables precise clamping and longer service life, and large capacity forged pipe jaws that securely clamp pipes and rods. Oversized, hardened jaws and anvil provide greater clamping on all work surfaces, while the steel handle's anti-pinch rings offer increased power and eliminate pinches.
