90 Degree Positioning Squares Aluminum Alloy 6" x 6"(16x16cm) Right Angle Clamps Woodworking Carpenter Tool Corner Clamping Square for Picture Frame Box Cabinets Drawers

I have used the smaller version of these right angles and they work great for positioning parts for assembly. I am not happy with these larger right angles. Starting with the cosmetics they are finished with a rough coating compared with the smooth, hard anodizing on the smaller version- result- dried wood glue is difficult to remove. The coating does not seem to be a hard anodizing so these angles seem to nick easily. Moving on, both inside legs have high spots (.001-.003) in the area just before the inside corner relief. I did not have any issues with the smaller version.

I do a lot of 1in sq tube welding and needed a solid 90 deg angle other than a 6in framing square to jig up my corners for welding. Not everything can fit flat on the weld table, I can use f clamps or 2 in spring clamps or vice grip locking C clamps work really good. Only thing to change would be to machine a 45 deg bevel for inside corner clamping. I may also add a flat plane on one face of the angle to provide additional clamping surface.Worth having in your tool kit for anything clamping project needs.

I purchased the 6” clamps as an aid to squaring up the corners of my canvas stretcher frames. The longer 6” sides allow me to use quick clamps to secure the right angles to the inside of the frames to true them up. I then can drill holes and install metal expansion brackets to secure the corners. I wish I bought this product years ago. I’m very pleased.

these appear to be well made, are accurate at 90 degrees and a good deal for the price. no complaints....

very sturdy brackets, have several others and never had a problem with them.worth the money.

No complaints.

Works as described well pleased

very high quality!
