Don't you hate it when all you want to do is tighten or loosen one simple clamp, and now you have to go hunting for the screwdriver? What's worse, perhaps you've already had a few drinks (yeah, we know, it happens), and now you're fumbling with the screwdriver to line it up with the screw head (with double vision, you only have a 50% chance of getting it right). Well, your problems are solved. Behold the Easy-Turn clamp. The Easy-Turn clamp is a reusable, worm-gear clamp manufactured from 300 series stainless steel. The 3/4" clamp is fully adjustable and will fit tubing ranging from 3/4" OD down to 1/2" OD. And what's best - you don't need a screwdriver. Any opposable thumb and forefinger works great, even in those circumstances when you've had a few!
