Check before ordering: extrusion profileCorner brackets, gussets and T-nuts are sized to a specific extrusion profile (commonly 20×20mm "2020" with a 6mm or 8mm T-slot, sometimes 20×40mm) — measure the spare extrusion's width and slot before ordering any hardware for it, since a bracket for the wrong profile simply won't fit.
