About a year ago I 'discovered' these Pony clamps and immediately declared them the go-to clamp for my shop.
Strong, stiff, easy to use, versatile.
Large clamping face, quick release (that doesn't PINCH :)), able to attach 2 clamps together for extended reach(!)
Unfortunately the Pony company has filed bankruptcy and these clamps disappeared from my local Menards.
Grizzly to the rescue!!!
I've been able to build collection up to 3 of the 18" (the best size of all!!!!), 3 24", 3 36" and even a token 8".
The lighter weight style Pony clamps are fantastic too. I'm getting another Grizzly delivery today and 6 more of these in various lengths this afternoon.
Get them before they're gone - guarantee you'll be a happy clamper ;)
