Woodworking Experience:
Square corners everytime
I haven’t actually used these yet but I’ve had the full size version for a few years now and they work great. I use them for boxes, tables and anything I need to glue up square. I even use them to make wooden squares. The larger size is great but not for smaller boxes and frames. You just can’t fit all 4 inside your box or frame so that’s the reason I purchased the smaller version. I see no reason they will perform any differently.

The nice thing is the clamps from the Big Boy Set work with these as well. As I make colonial style wall clocks, the make glue easy.

Work great for clamping anything at 90 degrees. Had purchased before and loved them, unfortunately, they were 'loaned' out and never got back. Guess they liked them too!

I make a lot of wall clocks, and my homemade clamps don't always work
Jim G on May 17, 2019
I love my full size clamps. I’m new to woodworking and found out that making cabinets and drawers square is a lot trickier than it looks. The minis will work well on smaller pieces.

Have had 4 of these for several years and always wish I had more when making multiple drawers which I do often. These work on smaller drawers when the larger ones won’t fit.

BEST ANSWER: Yes. They even supply bolts to attach it if you wanted.
can you use the 5" clamp with this instead of 4" clamp ?
dannyboy on Dec 13, 2016
BEST ANSWER: Dannyboy, the short answer is yes, it will work fine. In my opinion, the 5" is better than the 4" simply because you can clamp thicker wood against the Clamp-It Assembly Square, which itself takes up 2" of the space between the jaw-faces. (For what it's worth, the legs on the smaller Mini Clamp-It Assembly Square are only 1" wide, so you get more clamping space between the jaw-faces.) Hope this helps. Rich
