Adams Rite - 4085-40IN-X-96IN - Header Bolt - 40" Cylinder Height - 96" Door Height

The 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 (sold separately) in the active leaf.

Function: When combined with a 4015 Threshold Bolt in the active leaf and a pivoting bolt MS deadlock, this device adds a third locking point at the top of the door for pairs of doors. The inactive leaf has the 4085 Header Bolt installed on it. When the MS bolt pivots, a second bolt is fired, which expands in a scissor-like motion to align itself in its strike as it rises. Even if the doors are out of alignment as a result of poor installation or settling, this action spares the key holder the hassle of aligning up the doors with three consecutive strikes. A basic MS1850S, MS1850SN, or MS1950 Series deadlock can be upgraded to a Maximum Security three-point locking system by adding the 4085 Header Bolt and the 4015 Threshold Bolt.

Operating Principle: When the basic MS deadlock is turned 360 degrees, a counterbalanced bolt is thrown into the opposing door, kicking a positioner bolt into a header strike. To save key-bow effort, the positioner bolt can be manually fired before closing the active leaf. Only after the bolts are positively locked or unlocked can the key be withdrawn.
