The 6 hole - center inside corner bracket is an external fastening method that creates a 90 degree connection. One side of the bracket has four holes comprised of two rows and two columns while the second side has two centered, stacked holes. This bracket can be used to connect profiles that are within the same series but of different sizes. It requires no machining services and can provide infinite positioning along the profile T-slot, allowing a large degree of adjustability. The 6 hole - center 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.
