Function: 

Adding the 4015 Threshold Bolt to a pivoted bolt MS® deadlock provides Maximum Security for pairs of doors with the turn of a single key. Simultaneously dropping a stainless steel hexbolt into the threshold and pivoting the massive MS® bolt into the mating door’s stile, the two-point locking solution secures the entire entrance. The 4015 Threshold Bolt is harnessed to the rear of the pivoted bolt. It may be added to any basic MS1850S, MS1850SN, MS1950 Series deadlock. Both the 4015 Threshold Bolt and the 4016 Header Bolt may be added to a pivoted bolt MS® deadlock to provide Maximum Security for pairs of doors by the turn of a single key. Simultaneously extending the stainless steel hexbolts into the threshold and header and pivoting the massive MS® bolt into themating door’s stile, thereby providing a three-point locking solution.

Operation: 

360° turn of key or thumbturn in basic MS® deadlock throws counterbalanced bolt into opposite door and drops bolt into threshold. Key can be removed only when bolts are in a positively locked or unlocked position.
