The Adams Rite 4085-01-IB Header Bolt provides a top door third locking point for pairs of doors. The bolt is mounted in the inactive leaf, and works in conjunction with an MS® pivoted bolt deadlock. When this header bolt is triggered by the pivoted bolt, it expands to center itself in its strike as it rises, which saves the keyholder the task of liining up the doors on their three separate strikes. A thumbturn of the key throws the counterbalanced bolt into the opposite door, thus kicking the positioner bolt into the header strike. The positioner bolt can be manually thrown before closing the active leaf.
