This is an L-shaped internal connector for 2020 V-slot aluminum extrusion profiles, designed to snap into the V-slot channels of two profiles and join them at a perfect 90° angle.

Unlike external corner brackets, this connector is fully internal, providing a sleek and clean frame with no visible hardware. The friction-fit design ensures a strong hold without screws, making it fast and easy to assemble or adjust.
