The Long Throw Deadlock delivers a high-security locking solution for commercial storefront aluminum doors. Featuring a robust hook bolt mechanism with an extended 1-3/16" throw, this system enhances door engagement and resistance against forced entry. The lock body integrates an 8-ply laminated steel bolt structure, reinforced with a hardened roller pin positioned within a case-hardened center layer, ensuring exceptional strength and durability under repeated use. The kit includes both exterior and interior mortise key cylinders, enabling flexible access control configurations across different project requirements. A standard 1-1/8" cylinder backset supports compatibility with common door preparations, making it suitable for replacement projects or new installations.
