The only parrot that will help you in the workshop. Built like a machinist's vice, the Parrot vice incorporates a unique tightening cam that lets it pivot freely through 360 until you tighten the jaws firmly, locking the vice in place. The system lets you back off the clamp screw just enough to rotate the vice for access to any part of a workpiece without releasing it from the jaws. Further, the vice can be lifted from its heavy pivot post and reinstalled horizontally (either side up), maintaining the same pivoting and locking functions. 90mm (3.5") wide cast iron jaws open to 125mm (4.75"). There is a 45mm (1.75") square machined anvil just behind the jaws. The vice weighs roughly 8kg.
