This is what the set up looks like



There's space on the opposite side of the housing that holds the jaws with a semi-circle at the bottom where the lever fits in. The jaws are held in by the screw, you can see the knob above the tightening lever. I found that by sliding a rubber gasket over the housing helps maintain tension when the lever is opening or tightening the jaws. You can barely see it on the housing between the lever and the tightening knob.
