Got a bunch of those for free. No idea what they are for. Pretty lightweight stuff, not very sturdy. There seems to be some sort of adjustable clamping feature, kind of like an adjustable pipe clamp friction mechanism, when the "handle" part fits over the square tube. It seems to lock when the tube is pulled. (It has a roller that fits against the tube where it goes through the "handle".) Then can be released by squeezing the handle. But that's all conjecturing. Looks like this is the complete kit minus a couple of small bolts given sealed packages I have.
Somebody knows what this is?
