ABSTRACT:
A security bar for a door is mounted on retainers on each side of the frame of the door. Each retainer has a base surface, the inclination of which can be adjusted relative to the head of the retainer to accommodate door trim that inclines relative to the plane of the frame. The bar has slots on each end for engaging the retainer. One of the slots is parallel with the axis of the bar for sliding over one of the retainers. The other slot is perpendicular to the axis of the bar for sliding downwardly onto the other retainer. A sliding locking plate locks the bar to the retainer once in position. The retainers can be installed on wooden door frames, or on metal door frames. On metal door frames, a placement hole is drilled on the inside of the door frame to insert a barrel nut. A placement tool holds the barrel nut while tightening to a screw extending through the retainer.
