Review on ⚙️ Enhanced 20X20X17mm Aluminum Extrusion Corner Bracket: Superior Strength and Accuracy for Precise Assembly by Bobby Plymell

The product worked as expected, although you are wondering why they are not 20mm mounts when you are converting a 17mm mount to a 20mm set profile. The finish is a little rough, but exactly what you'd expect from cast aluminum. Overall, I would definitely use them again for another project that requires a 2020 frame.
