The Versa Vise pictured below is the 2nd vise purchased...the first was returned because the screw and nut didn't engage...the jaw didn't move at all.
This Versa Vise has the angle attachment which allows the vise to be tilted front to back. It came w/ a palm screw that didn't tighten enough to hold position, so I bought a hex head bolt tightened w/ a wrench that works. It's in the back.
Bought this vise for light duty clamping and it barely does the job. The screw has to be turned 3 times before the jaw moves which is irritating and the clamping force is minimal.
The only really good thing about this vise is that it has smooth jaws.. I'm on my last LR so won't be using the Versa Vise very often.....Fred
