When working on projects involving 20x20 extrusions, these corner brace supports are indispensable. Crafted from cast aluminum, they offer superior strength compared to extruded corner supports, ensuring a solid connection for your construction needs.Featuring two strategically placed holes, one in each corner, these braces allow for easy connection of two pieces at a 90-degree angle, enhancing stability and precision in your build.Please note that each brace support is sold individually. For complete assembly, you'll require T-nuts and 8mm long screws; 10mm screws are too long and may compromise the integrity of the support. https://elecena.pl/product/29464294/adafruit-aluminum-extrusion-corner-brace-support-for-20x20 2025-10-30 https://elecena.pl/product/29464294/adafruit-aluminum-extrusion-corner-brace-support-for-20x20 2025-11-01 https://elecena.pl/product/29464294/adafruit-aluminum-extrusion-corner-brace-support-for-20x20 2026-04-13 https://elecena.pl/product/29464294/adafruit-aluminum-extrusion-corner-brace-support-for-20x20 2026-07-01
