Special Use Clamps
Retract Clamp
Single Acting Available in 1,700 and 3,300 lbs capacities. Extends straight forward, then down to contact your part. Replaceable spherical contact point (furnished) provides point contact for true vertical clamp force. Lifts vertically, then retracts, not like others which can draw the part when unclamping. Patented design overcomes the shortcomings of other models. Integral wiper helps keep chips and contaminants out of the mechanism. Manifold mounting port is built into each unit, making selection easy, no special models to order. Rear and side porting are included for ease of plumbing in your application.
