<p>A slide bolt unit is provided for releasibly locking a door or window or the like, such as a semi-active door in a double door entry set. The slid e bolt unit includes an elongated slide bolt carried by a channel-shaped housing adapted for recessed mounting into a side edge of a door or the like . An actuator tab on the slide bolt is exposed through a position control sl ot formed in the housing for fingertip actuation to displace the slide bolt between an advanced position engaging a keeper on an adjacent header or sill or the like to lock the door in a closed position, and a retracted position to perm it door opening. The actuator tab has a slotted profile defining lock shoulders biased by a spring for releasibly engaging and locking with the housing at opposite ends of the position control slot, and a narrowed central slide tra ck for alignment with the position control slot upon fingertip depression of th e actuator tab to permit quick and easy sliding displacement of the actuator t ab along the position control slot from one end to the other.</p> |
