### ⭐⭐⭐⭐⭐ These ARE the Real Deal!
*by G***. on June 18, 2024*

If you are a professional in the iron/ metal working industry These are the clamps you need to buy/ work with! I began working in industry in the 1970s and 80s and these rival the quality of tools that were available to us back then. Solid, over 4” deep and acme thrd clamping rod exceeds 3/4” dia.
