Corner brackets are L-shaped connectors used to join T-slot aluminum extrusions at a 90-degree angle.
They are vital for building frames, enclosures, and various structures with these profiles. Made from aluminum alloy for strength and compatibility, they typically have holes on each flange for screwing into the T-slots of the extrusions.
