These plates serve as the breakable element in a pull station, allowing authorized personnel to activate a door release or alarm by applying direct pressure to the glass. The 491-GL4 is sold as a set of four individual plates per unit of measure, making it practical for facilities that cycle through plates during regular testing cycles or after activation events. Installation and stocking of these plates is handled by security integrators, access control technicians, and facilities maintenance personnel.\u003c\/p\u003e\n\u003cp\u003eThese replacement glass plates are suited for commercial and institutional facilities where SDC 491-series access pull stations are already installed. Typical applications include egress door control systems in office buildings, healthcare facilities, schools, and other occupancies requiring compliant manual-release hardware. The plates are used to restore a pull station to service after the glass has been broken during an activation or a scheduled functional test.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSet of 4 replacement glass break plates per package\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for SDC 491-series access pull stations\u003c\/li\u003e\n  \u003cli\u003eAllows quick restoration of pull station to operational status after activation\u003c\/li\u003e\n  \u003cli\u003eSupports routine testing programs without sourcing individual replacement components\u003c\/li\u003e\n  \u003cli\u003eOEM-matched fit eliminates need for field modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as OEM-style replacement glass plates for SDC 491-series access pull stations.
