Description

Product Description & Features:

• Designed to add a top-of-door third locking point for pairs of doors with an MS pivoted bolt deadbolt and 4015 Threshold bolt in the active leaf.
• The 4085 is mounted in the inactive leaf. This additional bolt, triggered by the pivoted MS bolt, expands in a scissor 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.
