Adams Rite MS1851SW Series MS® Deadlock, Radius Faceplate with Weatherstrip, any Handing
The MS1851SW (Adams Rite 1850S Series) MS® Deadlock - Radius Faceplate w/ Weatherstrip utilizes a laminated stainless steel bolt to provide maximum security for a single leaf narrow stile aluminum door.
A huge bolt of laminated stainless steel, nearly 3" long, activated by an uncomplicated pivot mechanism, has made the basic MS1851SW (Adams Rite 1850S Series) MS® Deadlock the standard of the narrow stile aluminum door industry. The length of this bolt provides maximum security for a single leaf door, even a very tall and flexible one or an installation where the gap between the door and jamb is greater than it should be.
