Connecting aluminum extrusions together is important, and so is having a lot of options to accomplish this! These stainless steel “L” shaped brackets / side plates are designed with 2020 Aluminum extrusion in mind and are intended for right angle connections. The plate significantly increases the strength of right angle connections and is ideal for improving the rigidity of your structure. The plate is constructed with 3mm stainless steel and measures 65 x 65mm. The included drop-in T nuts mean these plates can be added after the structure has already been assembled, no need to have access to the slot ends.
