90 Degree Positioning Squares, Clamping Square, Right Angle Clamp Corner Clamp Woodworking Tools for Wood Cabinets, Carpenter Tool for Photo Frames Box Drawer, Set of 12（3" 4" 6")

Works like you expect

I thought this would be super cheap and flimsy but what the heck, they weren’t expensive so I gave them a try. They arrived and are solid and square. They make cabinet and drawer building a breeze. I bought more!

I purchased these to compliment a pocket hole jig i bought, while they are a bit smaller than i thought, they look like they will hold up well for their intended use

I find these useful for making drawer boxes in my cabinet business. The small ones are handy for narrow boxes where larger ones won't fit.

keeps things square. works as advertised

Nice assortment

I really liked the idea of being able to square up a box with these. I bought universal fence clamps to go with them. I was hoping they would work well together, but what I really needed was corners with holes for the clamps. So, the mod I made was to drill holes in them. Now, they work perfectly. I suppose I should have been using standard ratcheting clamps, but the small corners would simply be too small for those clamps. The mod does work though.

Within a few tenths of a degree of 90 so should work well for hobbyist work. If you're seeking absolute precision for a more demanding application than typical woodworking then you may wish to look elsewhere.
