it's to dark for pictures and digging mine out now. If the bolt with the shaped loose fit piece on the end is what you are talking about. Is used to hold the vise in place. The idea is you place a section of pipe on top and point up to touch the ceiling, tighten the bolt till it locks the vise in place. It does work up to a point, as it can come loose if you really GO rilla it. And yes the bending of electrical conduit is what the holes and saddles are for. You only bend short leg/stub 90's with it. the long leg being out and up above the center tray. Since it is easier to use a hickey bender for up to 1" even intermediate conduit. The ridig bending shoes are pretty much ignored. Since with the intermediate conduit you really need the vise locked down or lag screws thru the holes in the feet of the legs.
Been there, probably broke it, doing that!
