Clamping Squares for Woodworking, 6.3" x 6.3" 90 Degree Positioning Squares Right Angle Corner Clamps for Woodworking, 16 x 16cm Aluminum Alloy Corner Clamp Tool for Picture Frame Box Cabinets

Good quality and smooth edges. It works as expected. You can get a decent amount of torque with these.

They are solid and will be very useful for my needs. The price seems right.

The set works well. Square enough for my use and I don't use the measurements engraved into the clamps for anything but very rough reference points. As long as you do not plan to use the clamps for measuring you should be fine, just be aware that these are clamps and not precision tools...

Clamps seem very well made, are fairly inexpensive, and will come in handy on your woodworking projects.

Disclosure, I was sent this corner clamp for review. That being disclosed, I was also only sent one corner clamp for review so I have no idea how the four pack is packaged. On with the review!My initial response was, “very nice quality corner clamp, what am I supposed to do with one corner clamp.” Upon further review of their link, it looks like these are sold in a four pack, I only received the one for review. The finish on these corner clamps is nice. Looks and feels good. Solidly made and most importantly, looks to be straight and square. The inside corner cutouts are nice, allowing you to use these on inside or outside corners. If you do a lot of larger boxes or drawer making, these get an extra thumbs up for being slightly larger than many of the 5.5” corner clamps on the market. Over all, a very nice addition to the wood shop, I wish they had sent me the full set.

This is a tough one. The square is for sure a quality made item. It is sturdy and holds the pieces firmly. However it is somewhat cumbersome. Lining up the corners, then tightening each side individually can leave room for errors. Especially if you are doing four corners. And they don't like to let go once you unscrew the knob. I unscrewed the knobs but the red holder stayed stuck on the threads (see pic 3). So for a short summary, is it quality? For sure-absolutely. Is it useful?.. Depends on the time you are willing to put into holding a corner square... I hope this was helpful.

This is a solid right-angle positioning square that I've been meaning to get for a while. It's a simple device, just a solid chunk of aluminum that lets you accurately set two sides of a cabinet, picture frame, door trim, or wooden box at perfect 90 degrees to each other. It becomes a "third hand" when you're trying to clamp, glue, and screw something together without distortion, or when you're trying finish a setup for welding or grinding.You can do inside or outside corners with this square, which has handy inch and centimeter rules to aid in positioning. It has countersunk holes that will allow you to screw the square down to a board, creating a semi-permanent jig for making picture frames (what I'm using it for).The square includes three separate placement holes for inserting the two threaded L-brackets into the stand-off eyelets. Securing the frame to the board is fast and easy, thanks to the large thumbscrews.This set works really well for smaller framing trim, and the usual 3/4-inch boards. My only real nit with this set is that it really limits you to working with items that are only up to 2 inches wide and about 7/8 inch thick. Picture frames, standard door trims, etc., can be much larger than that, so we'll be purchasing some longer threaded brackets.

Haven't had much use for them yet but they do work and are easy to work with

These clamping squares are a bit longer than most by about an inch and will help with larger projects . Overall they are very solid and should not bend with even a large amount of abuse . A bit pricey but sometimes you cant afford to buy the cheap stuff .
