Clamp is a device to hold an object in a fixed position. During secondary school, when we do some experiments in lab, we have used clamps to hold an object to complete our experiments. After I leave from school, and although I have clamp at my home, I have never touch clamps anymore because I don’t use clamps for my work. Anyway, for those people who are looking for clamps, perhaps you can check out reidsupply.com today!
