The 8 hole - gusseted inside corner bracket is a strong, external fastening method that creates a 90 degree connection. It has four holes, comprised of two rows and two columns, on each side of the bracket. It requires no machining services and can provide infinite positioning along the profile T-slot, allowing a large degree of adjustability. The shape of the gusset provides extra material, strengthening the connection. The 8-hole gusseted inside corner bracket engages the 2-degree drop-lock feature when the assembly bolts are tightened to the required torque. It is a fastening method that can be repositioned and reused. The suggested mounting hardware can be found on the "Suggested Hardware" tab.
