Schlage B662 Double Cylinder Deadbolt, Primus Cylinder
Product Description
The Schlage B662 Primus is a commercial-grade, heavy-duty Grade 1 double cylinder deadbolt designed for maximum physical security and advanced key control. Engineered to withstand high-impact physical attacks, drill attempts, and forced entry, this deadbolt requires key operation from both the interior and exterior sides, making it an ideal choice for exterior doors with glass inserts or narrow-stile commercial entries.
Equipped with Schlage's high-security Primus cylinder system, this deadbolt provides a dual-locking mechanism utilizing side pins and a specialized sidebar alongside standard key pins. Accommodating standard door thicknesses from 1-3/8" to 2", the B662 combines an anti-drill, anti-saw solid steel bolt with restricted key duplication to protect high-security commercial, institutional, and government facilities.
