发明名称 Safety lock for sliding glass doors
摘要 A safe and taper resistant safety lock system for the top of sliding glass doors and consists of a metal bracket fastened to the top edge of the door, positioned on the door with a screw which is normally found in each door, and then permanently fastened to the door with a second screw. A top, horizontal section, is formed by bending a first end of a metal plate, and extends over the top of the sliding door. The safety lock system is adjusted to reduce the gap between the top of the door and the top of the upper track to prevent lifting of the door out of the bottom track.
