I've had this for awhile now, and wondering where I'll mount it. She's a bruiser, rotates in the holder 360 degrees. 14" in height, 3.5" of flat jaws with pipe grippers below that. It appears there might be room for a post support on the bottom, or perhaps for a tool to be inserted for leverage (1" opening). Gotta weigh in at 40-50lbs.
I've not found a similar one on the web. No name. Probably was red originally. Flat 90d anvil platform.
Pipe vise?
