Adams Rite MS1850S-X5X Laminated Stainless Steel Hookbolt Deadlock for Sliding Narrow Stile Doors

Maximum Security Deadlock for Sliding Narrow Stile Aluminum Doors

The Adams Rite MS1850S-X5X Series MS® Deadlock provides maximum security for sliding narrow stile aluminum doors with its laminated stainless steel hookbolt design. This commercial-grade deadlock features a massive hookbolt measuring 5/8" x 1-3/8" with 13/16" throw, specifically engineered to resist the parting motion of sliding doors.
