Deadbolt Lock

The C11 Dead Bolt with T21 Double Cylinder Trim combines a heavy-duty deadbolt with key-controlled operation from both sides of the door. The T21 trim uses a cylinder on both the exterior and interior sides, allowing the deadbolt to be locked or unlocked by key from either side.

The deadbolt incorporates a steel ball engagement feature that strengthens the locking point. Steel ball engagement enhances resistance to jimmying and increases holding strength, providing additional protection against forced entry.

The double-cylinder configuration is particularly suited to jail, detention, correctional, and other restricted-access applications where interior thumb-turn operation is not preferred. Key operation on both sides provides controlled access and prevents direct thumb-turn operation from the interior.

With Grade 1 performance and durable construction, the C11 is suitable for high-traffic institutional and commercial applications where security and durability are critical.
