Von Duprin 377T US10B Thumbturn Trim Classroom Function

Product Description

The VON DUPRIN 377T US10B is a Grade 1 thumbturn trim designed for use with compatible panic exit devices in classroom function applications. Finished in dark oxidized satin bronze oil rubbed (US10B), this trim provides a durable, non-handed design that installs on either hand of door without modification. Grade 1 construction meets the demands of commercial and institutional environments where security, reliability, and code compliance are required. Licensed locksmiths, commercial door hardware specialists, and security contractors are the typical installers for this type of trim assembly.

Classroom function trim is suited for educational facilities, government buildings, and commercial properties where controlled egress and selective entry are required. In classroom function, the lock can be secured from the corridor side with a key while always allowing free egress from the inside via the thumbturn. This trim pairs with compatible VON DUPRIN panic exit devices to complete a compliant door hardware assembly on single or paired door configurations.
