MS1847 Series MS® Deadlock/Deadlatch

The MS1847 Deadlock/Latch for ultra-narrow stile aluminum slidingdoors features a self-protecting bolt with adjustable bolt projection.


A compact lock designed to fit within very narrow sliding door stiles without compromising the high degree of security that these doors need. The sturdy stainless steel bolt has two important features not usually found in sliding door hardware. First, it is adjustable: a full 3/16" [4.8 mm] lengthening or shortening of bolt projection is possible by turning an exposed screw in the face of the lock. This can compensate for considerable misalignment between door and jamb. Second, the bolt is self-protecting: if the door is closed with the bolt in the locked position, the bolt will retract immediately upon contact with the jamb. This automatic latch can prevent damage or accidental lockout.


Cylinder pulls are available separately for keyed operation. Three hub slot positions allow installation even where jamb and stile design provides severely limited turn clearance.


Case: Measures 1/2" x 3-3/16" x 1-1/8" [12.7 mm x 80.97 mm x 28.6 mm]. Stainless steel.

Bolt: Three-ply laminated stainless steel. Designed to withstand approximately one-half ton of either horizontal or vertical force. Anti-lift bolt stops both door-from-jamb pry bar attacks and attempts to lift the door from its track.

Faceplate: Rectangular face or full radiused ends (see how-to-order table on back of catalog page for dash numbers).

Latch Version: The MS1847-11 and MS1847-13 feature the same stainless steel hookbolt, but the bolt is spring-loaded for automatic latching. All dimensions and available accessories for the MS1847 Deadlocks also apply to MS1847 Deadlatches.

Standard Package: Case-packed with mounting screws. Turn and cylinder pull available separately.

Shipping weight: 1/2 lb [0.23 kg].
