摘要

The present invention provides a cost effective security locking mechanism for improving the security between a frame member and the masonry surrounding the frame member and additionally for enhancing the strength of engagement between the frame and a door associated with the frame. A substantial proportion of any force exerted on the door, when in the locked condition, is transmitted directly to the masonry surrounding the frame by means of auxiliary bolts and tubular metal anchorages.
