Security Door Controls 492-GL4 Glass REPL RODS

The SDC 492‑GL4 is a set of four replacement glass rods intended for the 492 Emergency Pull Station made by Security Door Controls. These rods are the break‑glass components used to activate the pull‑station in an emergency by physically breaking or removing the rod. They are packaged in sets of four so that spare rods are available to quickly restore the unit’s functionality after activation. These glass rods are compatible specifically with the 492 Series emergency pull‐stations. The product does not include the full stations, just the rods, making them a cost‑effective maintenance item. The set includes rods in appropriate length, thickness, and material to work with the break‑mechanism of the 492 model. They are supplied in a “pack” package type. The packaging includes information such as instructions or indications on how to replace the rods. They are made in the United States. They are considered a spare / replacement part rather than a full electrical / mechanical assembly. They are important in ensuring the emergency pull station remains functional and compliant with safety codes.
