These are high quality Jorgensen clamps at a bargain price of less than $5 each. However, because the clamp is so strong and the handle portion is so close to the hinge (closer than the jaw opening), you don't get much clamping force. I actually think they might work better if the jaws were curved a bit so you could reach the next position in the ratchet. I have no regrets buying them for $5 each. Not sure I would have bought them for 10 which is the current price if I hadn't known I need reach and not a lot of pressure.
