Used for attaching guard rails to arches. The design of the recess in the attachment plate means that different dimensions and types of screws can be used. In addition, the design allows for pre-assembly of the screw, then the bracket is placed in place and the screw is tightened. The low mounting height minimizes the torque in the fastening screw and enables shorter screws for better economy. The bracket is supplied with GuardLite Active Locking for silent mounting of the guard rail.
