Deadbolts are your first line of defense against a burglar. A deadbolt should be fitted on any exterior door to protect your family and possessions. Schlage deadbolts feature an exclusive patented steel strike reinforcer. B60 Series deadbolts use 76mm heavy gauge screws that penetrate through the door jamb and right into the wall stud. Add to that a full 25mm-throw deadbolt and you have an excellent deterrent to kick-in attacks. The deadbolt further features a hardened steel roller to prevent cutting and sawing attacks. Schlage's lifetime finish and lifetime mechanical warranties are standard on all B60 Series deadbolts when used in residential applications. Features include: Die cast chassis with pressed steel outer, adjustable 60/70mm backset with hardened steel roller in the bolt for added security, compatible with Schlage F Series locksets, and anti-pick shield.
