Nice piece!!! I didn't realize this when I ordered it, but the 3/8" thickness is the thickness of the plate that it is designed to go thru. I had to add a backer to increase the overall thickness of my plate. Still a niece piece of machining!!

Gret deal for tool, or....
As a professional diesel technician and instructor I build my own tools from time to time. Built this into a test and lift tool. Works for what I'm doing.
