Durable clip. Although I've seen some reviews pointing to breakage, this clip seems solid and durable. I clamped it over my workbench at 2" x 6" (true width 1 3/4") and was unable to make full face clamp contact with the beam due to an obstruction on the beam (smaller jaw at 3/4 depth against the tree .) However, he had a strong grip and if I had straddled them both like that I could pull them up, I'm not sure if Manfrotto is stronger but I can do it. LimoStudio.
