1-Sided Screw Down Vacuum Clamp Package Our vacuum clamps are great for use in CNC machines as well as for holding parts at your workbench and on the jobsite. Unlike other types of clamps, they grip the work piece from the bottom which leaves the top surface and all 4 sides free of obstructions and ready for routing, sanding, sawing, drilling, etc. Even when traditional clamps are a viable option, vacuum clamps can be an easier, quicker, and safer alternative. All of our vacuum clamp designs feature 9 square inches of surface area creating up to 125 lbs of clamping force (500 lbs total per set of 4 clamps.) Their extra-large clamping surface is especially important when working with porous materials, such as wood, where your vacuum pump may loose considerable holding power. Our 1-Sided Screw Down vacuum clamp package includes a set of 4 clamps, 6 ft of flexible vacuum hose to connect the clamps with, and a plug to cap the last clamp in the chain. To use the clamps, simply screw them down to your workbench or jig, run the hose from clamp to clamp in a chain, and attach your vacuum pump (not included.) Need more than 4 clamps for an extra large job? Just add a second or third set of clamps inline with the first set.
