Perform as expected

Bought this clamp to add to the bucket of other assorted clamps. It’s a lot lighter than the other ones the screws feel a little gritty but they are new. Overall they are a decent clamp for the money to have as an extra or for wood work

The slider arm traverses well, the screw tightens and loosens as you'd expect, however the 'top' of the F is crooked left to right a few degrees so you can't tighten either one of them straight up and down. Not perfect, still usable at least.

Nice clamps for my use as a weekend welder.

Fast Shipping, Lighter Duty Than Expected

These are probably good clamps for woodworking but I just can’t recommend for welding. They are extremely flimsy and I wouldn’t put much pressure or heat on them. Should have spent more money and got the one I know work for my application
