Stand back Autopts! I am about to flood this post with information. Some I made up and some the Internet made up. This is a Triple vise because it is a:
1. Woodworking vise
2. Bench vise
3. Pipe vise
It also has the Rapid Titan feature. Tighten the handle clockwise and it engages a nut ant moves the jaw inward. Opposite rotation disengages the nut allowing you to pull the jaw out without levers.
Yes....I am reading this off of a 1961 Wilton Catalog page that for some reason I can't get to download here. This vise also came with (and I kid you not) Masonite jaw covers for your hobby work!
