Adams Rite MS1837 Two-Point Deadlock, Satin Aluminum

Product Overview

The MS1837 Series Two-Point Deadlock offers maximum security for wood door pairs with the turn of a key. Simultaneously dropping a stainless steel 3/8" hexbolt into the threshold and pivoting the massive (eight-ply laminated steel with alumina-ceramic core to deter hacksaw attack) bolt into the opposite leaf, the MS1837 eliminates inconvenient and sometimes forgotten flushbolts in the inactive leaf. Key can be removed only when bolts are in a positively locked or unlocked position. Lock accepts any standard 1" (25.4 mm) length, 1-5/32" (29.4 mm) diameter mortise cylinder with MS cam such as the 4036 Mortise Cylinder or thumbturn such as the 4066 Thumbturn, available separately. Lock accepts cylinder from either or both sides.
