Brink & Cotton C-Clamp No. 144-4 inch
This is a nice vintage 4.0" capacity C-Clamp with the heavy duty cast steel design, marked "BRINK & COTTON BPT. NO. 144-4" U.S.A." on the frame. This clamp is in very good useable condition with no rust, straight, not bent, good pivot pad and threaded rod (the threaded rod is .556" diameter which is more heavy duty than others marked with the same number identification). This type of C-Clamp is made of top quality steel and is heavy duty, so these could be used in metal working.
