Grades and Ratings
Deadbolts are graded by the ANSI/BHMA scale, with Grade 1 being the strongest and best suited to exterior doors. Look for a solid one-inch throw bolt and a hardened steel core.
Single vs. Double Cylinder
Single-cylinder deadbolts use a key outside and a thumb-turn inside. Double-cylinder models need a key on both sides, which adds security for doors with nearby glass but can slow exit in an emergency, so weigh local safety needs.
