This is an external L-shaped corner connector for 20x20 V-slot aluminum extrusion profiles.
It joins two profiles at a 90-degree angle from the outside, keeping the interior of the corner open — perfect for clean frame geometry, panels, or enclosure corners.
The connector slides or snaps into the adjacent profiles’ ends, holding them together without the need for screws or T-nuts.
It’s strong enough for lightweight to moderate structures such as printer frames, LED boxes, or panel corners.
