The corner clamps are a well thaught and great item.
Awesome clamp, fits securely on my clamps and hold pieces very squarely.
The clamps are good at locking onto my squeeze clamps. I do find that they want to move a bit and not center on the joint which can pull the joint out of square. Overall a good product for the price.
Worked well but it was difficult to adjust them tight enough to stay on vs too tight as to not get them on. I used some tape to keep them on the clamp.
It make things a lot easier.

A grove of one part of a pair that slides onto the Irwin clamp broke because one of the raised parallel sides that make the grove, with the valley of the grove between the two parallel sides, was too thin and couldn't handle the pressure of sliding on and off the clamp. Other than that I found them to be helpful in putting the drawers together as directed in the plan of your medium 3 drawer cabinet.
I got the Jorgensen E-Z Hold clamps and they work great. They fit nice and keeps the parts at 90 degrees. I will use these a lot.
I took one star off for the box. If you pick it up by the top it opens up and everything falls out. They have very small, little, weak magnets that do not hold the led close. 3 times now I have pick it up and the top opens and everything falls to the floor. It's a nice box but not worth the money. Had to put a rubber band around it to keep it close.
Great tool!

It makes building drawers so easy. And the fact that they are now adjustable makes them even better.
They work great! Glad they have some adjustability built in to deal with different thickness clamp heads. Built my first set of drawers with them -- definitely speeds of the process, and improves retention of joint positioning during fastening process (pocket screws) over other clamping methods.
The case. Product as advertised
Love it!
Fit perfectly. Love them
Good
Nice little container or something for something I don’t use very often but when I do use it, I’d like it all
Just what I needed. Thanks
Great quality. Fit my large clamps perfectly. Easy to adjust and install. Going to order a set of the small clamps, just to have for my small trigger clamps.
Good
This clamp set is perfect. They fit my quick clamps, both Workpro and DeWalt. They work as described. Also, the box has magnetic plugs for the top and base, so the lid is securely held in place. And - a small allen wrench is included for adjustment. Zach's attention to detail pays off in quality builds. If you ever thought about corner clamps, these are well worth the investment! Thanks Zach!!
those accessories are great. thank you for it
they look great but i havent had a chance to use them yet.
Excellent for draws
Zach, I briefly tried using them for assembly of drawer boxes and the boxes were 9” deep. I had trouble using one clamp at the top of the corner on two sides and had alignment issues happening at the bottom of the corner. So I just winged it without the clamps. I will try them again on some not so tall boxes. I also think I may try using two clamps at each corner, one at the top and one at the bottom which may work better next time. Also, I think I was supposed to get the hinge template with one of my orders and did no receive it. If not so just let me know and I’ll order it. As for the assembly table I have the plans but haven’t built it yet.
Thanks, Nick ✌️
For really tall drawers I recommend putting a clamp on both the top and bottom of the drawer to hold the full joint in alignment.
The small clamps worked fine but there was one annoying feature:the adjustment on some of the clamps needed to be readjusted several times after each use. The clamps kept coming off and I had to really tighten down the adjustment in order for them to stay on. Otherwise, they worked great.
Great time saver.
I've been needing these for ever.
They work very well. Well designed.
This showed up on the same day I had all the material to build the lift table and they worked perfectly. I was so sick of trying to hold everything myself and this saved me a lot of time and errors.
These corner clamps are fantastic! They really made my drawer making process much easier!
I picked up a set of these and they worked great. Put these on a set of 6" trigger clamps and you a very fast way to help hold drawers at 90 Degrees. I don't find they provide much clamping force, but I don't they need to do that. They algin the edges and hold it at 90 degrees so you have two hands free to micro adjust and pin the drawer in place while the glue sets up. I found you can do a whole drawer this way and by the time you are done you can remove the fronts and go right the bottom to lock into square. I've seen other solution and used some. The trigger clamp is the fastest simplest I've used. I like them so much I'm leaving them on a set of clamps permanently.
They have really proven their worth making square corners. Be it for small cabinets or drawers.
