Overview

Effective August 2026, the Falcon T Series cylindrical lock is discontinued as part of the rolling transition to the modernized Falcon TM design that began June 2026. Available to order now, TM is designed to preserve the look, fit, and application versatility customers know today while introducing internal improvements that enhance durability, simplify installation, improve electrified performance, with additional functions and RX option. Direct TM equivalents are available for all functions with the exception of three T functions (T351, T411, T521).and the lead-lining option, which is no longer offered due to low demand.

For open Falcon T specification projects, our sales team will work with customers to transition to the new TM design or available substitutes. Falcon TM will replace legacy Falcon T designs for warranty requests. Select T tailpieces will remain available to order to service existing T locks. For any questions or concerns, please don't hesitate to get in touch with Technical Support at 1-877-671-7011, option 2 or Mechanical_Locks_TechProdSupport@allegion.com.
