Only used the 1/2" size so far
Worked well. Getting the straps in place took a little learning (keep enough tension for the corner pieces to stay in place, but loose enough to slide the next corner in). Almost perfectly square right from the start.

Great quality but...
I must have done something wrong cutting the box joint fingers because these cauls didn't fit. The box I made is 6 inches tall. The caul fingers started out right at the bottom but were off by about half a finger at the top. I measured the spacing on the cauls and they were exactly right for the 3/8 size I needed. Some minor error added up in the way I cut the wood in the first place. My fault, not the cauls.

Box Cauls Box Joint Jig
The jigs work well. They save a lot of effort when aligning the box joints squarely and true after gluing. Simply use a band clamp.

Did not work for me.
When I saw the video for these cauls I thought it was an ingenious idea. I ordered this set because it contained all of the cauls that I would need. I usually love purchasing items from Rockler because, even though they are a bit pricey, the quality is always excellent. Not so much with these cauls. I used the Rockler Router Table Box Joint Jig, and cut 3/8 in. box joints. When I went to clamp it up using the cauls, most of the pressure points were on the fingers of the joint, but two of them overlapped with the end of the finger of the adjacent piece. No matter how I adjusted the cauls, I couldn't get all of the pressure points on the fingers, which made these useless. I have returned them for a refund.

I recently completed a box with 1/4" box joints but I didn't have anything to help with the gluing. After reading the reviews and watching the short video I thought I would give these a try.

Tried making my own but they just weren't precise enough. These should work better.

Can these cauls be used on a 12" tall box or even taller?
George J on Nov 20, 2019
BEST ANSWER: Just did a 10” tall box and they worked great. For taller boxes you double them up.
Does this device "square" the box, or do you need additional methods to ensure squareness?
George J on Nov 21, 2019
BEST ANSWER: If you have cut the joints closely then it will pull in with one or two straps, but it never hurts to check the squareness of it.
