This is a good clamp but not for its intended purpose. I love making picture frames and the problem I had with this clip was that it would slip off the frame, especially frames three quarters of an inch thick or less. The plastic components seem too smooth and maybe something with a grip or texture to hold the wood more securely would be an improvement. For larger projects I think this would be a great clamp. I love the screw mechanism for tightening the clamp and you have plenty of room for rope for very, very large projects. But again, for making small photo frames 11x14 or 8x10, it doesn't seem to shrink without slipping.
