Well worth the investment! On advice from others I bought two for constructing a bath vanity. They held the plywood panels together very snugly to counteract the Kreg screws tendency to pull a panel slightly inward.

This clamp works flawlessly every time. Conceptually, it's very simple. It replaces one of the flats on a normal Kreg clamp with a pin that fits in the pocket hole. Use the clamps in one or more pocket holes while you drive the screws into the others. If you need 100% square accuracy, you can hold a square in place against the joint while you drive the screw.

By the way, you can use these to clamp items that are not flush to one another, e.g., frame reveals, parts with differing thicknesses, and inset panels. Try THAT with a corner clamp!

To the reviewer that wondered about using pocket holes on the outside of items: In cabinet making, it's the INSIDE of the cabinet that's the concern. The ply or particleboard sides and back of the cabinet are completely hidden for most cabinets and virtually always covered on end cabinets.

As to the review that talks about blowing out the pocket hole, the only things that could possibly cause that are drilling too small a pocket (the clamps work perfectly with Kreg drills), clamping so tight as to crush the pocket, or clamping at an extreme angle (the clamp will work at a range of angles, not just 90 degrees). Or perhaps the owner has a defective clamp. In any event, this is a highly unusual complaint, and I've yet to hear from anyone else with this problem. Trust your own judgement, though, go to a demo at a woodworking show or store and try them.

This is a great product but if you look around you can find this clamp cheaper.

I bought two of these clamps and glad I did. On occasion, I use to hold the wood in place on both ends or at a corner. I can drill a hole, clamp it then drill the other end and/or adjoining board, knowing the boards are going to be precisely in place when I put in the screws. Now its not moving.

The quality is good and will last a long time. It is amazing to me still how well they can hold at a right angle. It really works!

I easily recommend these and they make the finishing touch just a little easier for me.

Great clamp for Kreg's pocket screw holes. I order the extra clamp to go with the kit I purchased earlier. Good buy
