Dayton 2TGJ3 Fusible Link For Fire Damper Systems

The Dayton 2TGJ3 Fusible Link automatically releases fire damper mechanisms in HVAC safety systems when the surrounding temperature reaches 165°F (74°C), providing automatic thermal actuation for fire and smoke containment. Designed for installation in fire dampers, ventilation systems, air handling units, and ductwork assemblies requiring thermal actuation, it features metal alloy construction and mounts via a mechanical link connection with an actual width of 1/2 in and a height of 1-1/2 in. This UL Standard 33–compliant device, MPN 2TGJ3 by Dayton, is compatible with Dayton dampers 2TFZ4 through 2TFZ9 and serves replacement, repair, and safety maintenance to ensure reliable damper operation during fire events. Common replacements include Dayton 2TGJ2 Fusible Link, Ruskin 165°F Fusible Link, and Lloyd Industries 165°F Fusible Link.
