I work alone in my shop and these clamps are doing what I hoped and bought them for. They're the ones that are so necessary for an extra pair of hands for holding racks, mounts, etc. on a deep level. They also allow you to adjust the clamped wood to achieve the perfect height and position. I was concerned that I had just bought an expensive tool that would rarely be needed. Not even close. Cons: If you are not careful, you can pinch the skin of your finger. Pros: The tension of the clips is adjustable, helping to get the right tension and keep the skin out of the clip.
