Woodpeckers M2 Box Clamp

NEW! From Woodpeckers, the M2 Box Clamps. There like Having an Extra Pair of Hands. With our M2 Box Clamps you can glue-up or dry-fit any 90° joint quickly and easily and know your joint is square. They quickly adjusts for use with material ranging in thickness from a ¼ inch to a full 1 inch. And with a twist of the knob or the turn of a hex key, depending on your clamping application, provides ample torque to tighten the clamp, square your stock and secure the joint.

Just ordered a set because one of the biggest frustrations re keeping a box square - clamps that are a pain in the rear to use - has been admirably solved with these clamps. The only improvement would be to add a slot or hole to hold the allen key so it's accessable when you need it and you're not searching constantly for the darned key. Excellent product.

I've always had an attraction to the M2 Box clamps. Some nice improvements. The only hang up I have is the need for the allen key. A quick release feature instead of the socket head cap screw would push me off the fence.

When I needed to fabricate w acrylic clamps worked well without marking material.

I own a couple sets and they frustrate me with box joints. I leave 3/16" proud on my 1/4" box joints and the square piece on the outside causes a 1/16" gap in the joint as I tighten them up.

Come on Eric! Smart guy like you could come up with a speedy way to get around that Allen screw! Look what you did with the kreg auto max clamps and the mft table!

I really regret purchasing these. Maybe I misunderstand the product, but I believed that they would help *make* corners square. But after multiple uses, that dosent seem to be the case. You need to get your corners square ahead of time and these (I guess) can hold them square. It’s cumbersome and slow to set these up. You don’t get positive feedback when tightening and it’s very hard to tell when you’ve tightened enough.

Maybe these are useful for some of the other tips, like holding pieces while you drill/drive. But as glue up clamps I hate them. Own about half a dozen Woodpeckers tools and generally happy with the rest.

I bought the first version that only works on 3/4 boards. Not great. Just okay. A regret purchase TBH
