Enhance entry door security with the Prime-Line U 9972 Jimmy-Resistant Deadlock. Designed to help protect against forced-entry attempts, this surface-mounted deadlock features a proven jimmy-resistant design that helps prevent door frame spreading, prying, and other common break-in methods. Ideal for residential entry doors, this lock provides an added layer of security without requiring extensive door modifications.
Constructed from durable diecast metal with a corrosion-resistant brass-colored finish, this deadlock is built for long-lasting performance and classic appearance. The surface-mounted cross-bolt locking mechanism helps secure the door firmly to the jamb for increased resistance against physical attack. A tamper-resistant shutter guard helps protect the keyway from debris and discourages tampering, while the double-cylinder design provides keyed operation from both sides of the door for controlled access.
Designed for use on wood, metal, and resin doors measuring 1-3/8 in. to 2-3/8 in. thick, this deadlock installs using common hand tools and included mounting hardware. The complete kit includes the lock body, angle strike, keys, and installation components, making it an excellent solution for door security upgrades and replacement applications. Review door dimensions and installation requirements before purchasing to ensure compatibility.
