Header Bolt with Header Strike, for Inactive Door Leaf, Used with MS1850, MS1890 Series Deadlock, 7ft Door

Adams Rite Manufacturing

4085 Header bolt provides top-of-door third locking point for pairs of doors when working in conjunction with an MS pivoted bolt deadlock and 4015 threshold bolt in the active leaf. Designed to add a top-of-door third locking point for pairs of doors when used in conjunction with a pivoted bolt MS deadlock and 4015 threshold bolt in the active leaf. The 4085 header bolt is mounted in the inactive leaf. This additional bolt, triggered by the pivoted MS bolt, expands in a scissor-like action to center itself in its strike as it rises. This action saves the key holder from the difficulty of lining up the doors with three separate strikes, even if doors are misaligned due to faulty installation or settling. The 4085 header bolt can be added to any basic MS1850S, MS1850SN, MS1950 series deadlock with the 4015 threshold bolt for a maximum security three-point locking solution. 360° turn of key or thumbturn in basic MS deadlock throws counterbalanced bolt into opposite door, kicking positioner bolt into header strike. Positioner bolt may be manually thrown before closing active leaf to reduce effort on key-bow. Key can be removed only when bolts are in a positively locked or unlocked position.
