Adams Rite MS1850SN450628 Deadlock Flat Faceplate Hook Bolt

Product Description

The ADAMS RITE MS1850SN450628 is an ANSI-size MS series deadlock with a flat faceplate and 1-1/2 inch hook bolt, finished in clear anodized aluminum. Designed for narrow stile aluminum door frames, this deadlock delivers the mechanical security and clean profile that commercial door applications demand. The hook bolt design resists spreading attacks on the door frame, making it a reliable locking solution for high-traffic commercial, industrial, and institutional openings. Licensed contractors and commercial door hardware specialists install this unit as part of complete aluminum door assemblies. At 1.5 pounds, the hardware is compact but built for demanding service environments.

This deadlock is intended for narrow stile aluminum door openings in commercial, industrial, and institutional construction. It fits applications where a low-profile flat faceplate is required to maintain flush door aesthetics while meeting access and security code requirements. The clear anodized aluminum finish blends with standard aluminum storefront and curtainwall door stiles. It is sold as a single unit and is suited for new construction as well as replacement installations on existing narrow stile aluminum frames.

Installation Notes

Installation should be performed by a licensed locksmith or commercial door hardware technician familiar with ANSI-standard MS lock mortise pockets. Verify the door stile width and existing cutout dimensions before installation to confirm proper fit. Disengage all power to any electromechanical door hardware in the assembly before beginning work. Follow local building and fire codes, including applicable provisions of NFPA 80 and IBC egress requirements, when installing locking hardware on exit-path doors.
