Review on KAKA Industrial Construction Heavy Duty Cast Iron: Ultimate Strength and Durability for Any Job by Max Rosengren

This 90 degree clamp is very strong and I am very impressed with the finish. It costs a lot more than some of the other similar models, but it's also a lot heavier than the cheaper imitations. It also lies flat, unlike reviews that mention less expensive knockoffs. I can't imagine this clamp ever warping or breaking. I would definitely recommend this to a friend.
