01 / OVERVIEW

Overview

The C11 Dead Bolt with T23 Single Cylinder Trim combines a heavy-duty deadbolt with a single-cylinder configuration and an interior indicator thumb turn. The exterior side is operated by key, while the interior side uses a thumb turn with an indicator, allowing convenient operation from inside and clear indication of the lock status.

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 T23 configuration is suited to bank strong rooms and other restricted areas where controlled exterior access and clear interior lock status are required. The indicator provides a quick visual reference of the lock status for authorized users.

The C11 Series is built for demanding security applications where strength, durability, and controlled access are critical. Its Grade 1 performance and ANSI/BHMA A156.36 compliance make it suitable for financial institutions and other high-security environments.
