4085-02-IB Adams Rite Header Bolt for Pairs of Doors

The 4085-02-IB series header bolt is the top-of-door third locking point for pairs of doors when working in conjunction with an MS pivoted bolt deadlock. The 4085 header bolt is mounted in the inactive leaf. This additional bolt when triggered by the pivoted MS bolt, expands in a "scissors" 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 three-point features may be added to any basic MS1850S/MS1850SN or MS1950 deadbolt. It operates with 360 degree turn of key or thumbturn in basic MS deadlock throws counterbalanced bolt into opposite door thus kicking positioner bolt into header strike. Positioner bolt may be manually thrown before closing active leaf to reduce effort on key-bow. The key can be removed only when bolts are in a positively locked or unlocked position.
