Adams Rite 4015-18, Threshold Bolt, Std Height

Adding the 4015 bolt to a pivoted bolt MS deadbolt allows Maximum Security for pairs of doors by the turn of a single key. Simultaneously dropping a hardened steel hexbolt 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.
