🔧 KOOTANS 1Pc 90 Degree Corner Angle Bracket Connection Joint Strip for 10Mm Slot 4545 Aluminum Profile 3D Printer Frame Review

Nice strong but very light aluminum corner braces that I will be using to reinforce the corner on two extruded aluminum pieces. I just wish they were a little cheaper but I will be buying more as I have more corners that I need to make strong and they will do the trick.

Product quality is good. No sharp edges. Lasting finish. The first set ordered had the complete equipment. The second set is missing 6 screws. As you can see from the photo there are 6 nuts but no matching bolts. One screw had a bad hex, but most likely the problem isn't with the suppliers. Update: 07/30/21 The seller contacted me and solved the problem immediately. Excellent customer service. I would highly recommend them and will buy from them again.

These mounts are precision machined and free of burrs or tool marks such as nicks or flared holes. Perfectly smooth. Material - heavy aluminum plate. The finish is satin and I assumed clear iridite passivated or anodized. I used them as is but the surface can be painted if you wish. The price is great, especially considering you get the hardware (with appropriate T-nuts) to install with five bolts in 2020 profiles. My cube printer is extremely stable with these extra parts. Highly recommended.
