Adams Rite Commercial Deadbolt Less Cylinder, HD, Satin Chrome MS1850S-310-628
Door Deadlock, Flat Faceplate, Straightbolt, Non-Handed, 1-1/8" Backset, Clear Anodized, For Aluminum Door
A huge bolt of laminated stainless steel, nearly 3" long, activated by an uncomplicated pivot mechanism, has made the basic MS1850S 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.
360° turn of key or thumbturn projects or retracts the counterbalanced bolt. Key can be removed only when bolt is 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 4066Thumbturn, available separately. Lock accepts cylinder from either or both sides.
