4015 Threshold Bolt is a two-point lock that easily secures a double door entrance. Adding the 4015 Threshold Bolt to a pivoted bolt MS® deadlock allows Maximum Security for pairs of doors by the turn of a single key. Simultaneously dropping a stainless steel hex bolt into the threshold and pivoting the massive MS® bolt into the mating door’s stile, the two-point lock secures the entire double door entrance. The 4015 threshold bolt is harnessed to the rear of the pivoted bolt. It may be added to any basic MS1850S or MS1850SN deadbolt. Operation: 360deg. turn of key or thumbturn in basic MS deadlock throws counterbalanced bolt into opposite door and drop-bolt into threshold. Key can be removed only when bolts are in a positively locked or unlocked position.


  • Cylinder Height: Standard threshold bolt rod is sufficient for cylinder height up to 53-7/16". It is fully threaded and can be cut off for low cylinder heights. Also available to volume users, cut and threaded only for specific cylinder heights.
  • Adjustment: Exact adjustment of threaded rod to cylinder heights is locked in place by hexagonal threshold bolt.
  • Strike: For drop-bolt, a 1/2" diameter hold in metal threshold is suitable. For non-metal installation, 4005 strike is available.
  • Threshold Bolt: Hexagonal 3/8" flat to flat. Made of stainless steel.
  • Options: For "universal" application, specify 4015-18 with fully threaded rod for cut off to any cylinder heights below 53". For greater height or precut rod for high volume use, specify exact cylinder height.
  • Standard Package: Packed separately with bolt guide, screws, and attachment pin. Shipping weight: 1 lb.
