Adams Rite MS1850S-350-628 MS1850S Series MS Deadlock with Hook Bolt, 1-1/8" Backset, Flat Faceplate, Non-Handed, Clear Anodized

Deliver industry-grade security at critical access points with the Adams Rite by ASSA ABLOY MS1850S Series MS Deadlock. Built for single-leaf and sliding narrow-stile aluminum doors, this deadlock uses a laminated stainless steel hook bolt and over-center maximum security locking action to resist forced entry, prying and parting motions. The 1-1/8" backset and flat faceplate provide a precise fit in common narrow-stile frames, while the non-handed configuration streamlines inventory and installation.

Finished in clear anodized aluminum for long-lasting corrosion resistance, the MS1850S accepts standard 1" mortise cylinders and pairs with Adams Rite electric strikes (4000, 4001, MS4002) for seamless access control and monitored entry. Its 360° key or thumbturn operation ensures positive lock/unlock status and supports integration with surveillance and monitoring systems for comprehensive door security. Ideal for commercial, institutional and industrial applications where dependable physical security and easy system integration matter.
