Patent attributes
A slide bolt assembly is slideably engaged in an astragal disposed at a free end of a semi-active door in a double-door set. The slide bolt assembly includes an elongated base that slideably engages the astragal. The slide bolt assembly defines a threaded hole and a screw lock is rotatably disposed in the threaded hole between an unlocked position and a locked position to lock the elongated base within the astragal. The screw lock defines a central portion and a rim portion peripherally surrounding the central portion. The rim portion presents a contact surface that is planar. A nipple protrudes from the central portion further than the rim portion. When the screw lock is rotated to the locked position, the nipple pierces a wall of the astragal and the contact surface of the rim portion frictionally engages the wall to lock the slide bolt assembly within the astragal at any point along the astragal.
