About This Product

Looking to upgrade your home security? This Master Lock deadbolt is a solid, reliable choice that won't break the bank. The satin nickel finish looks sleek and modern on any door, and the single cylinder design gives you key access from outside while keeping the convenient thumb turn inside.

Rated ANSI Grade 3, it provides good security for residential exterior doors - not quite commercial grade, but definitely better than basic builder-grade locks.
