Supplied in packs of two, the UJK Technology Cam Lock Hold-Down Clamp offers ultra fast locking and quick release for all manner of fixtures and fences. They are easy to use, self-locking and exert plenty of force. These come with M6 x 75mm, tee-bolts; by substituting the tee-bolts for regular M6 bolts you have the option of using the Cam Lock wherever you wish. Screw the lever down until it is touching the top of the fixture/fence etc. Pushing the end of the lever down, applies considerable clamping force. To release the fixture, simply lift the lever. Each pack contains 2 anodised aluminium cam levers, 2 threaded cross dowels and nylon and steel washers.-bg
