Schlage B661 – One Way Deadbolt
Schlage B Series deadbolts have long been the industry standard for tubular deadbolts. Built Schlage strong, B Series deadbolts are among the most secure and durable in the industry. The commercial Grade 1 deadbolts are also among the most beautiful, with a sleek, broadly angled trim ring in a shallow, 7/8″ depth offered in 11 finishes. A wide variety of functions and choice of cylinders including geographically exclusive Primus XP options, makes them suitable for nearly any deadlock application need.
