This F clamp is a must-have for anyone working with industrial and scientific equipment. It's reliable, strong and precise, making sure that your work is always held securely in place. The copper material also adds an extra level of durability. The only downside is that it's a bit heavier than other clamps, but that`s to be expected with its level of sturdiness. Highly recommend for anyone in need of a top-quality clamp tool..
