It requires no machining services and can provide infinite positioning along the profile T-slot, allowing a large degree of adjustability. The 8 hole - 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.
