The STI STI-6519 is a single-gang hinged clear protective cover with mounting plate and continuous piano hinge. First, the installer fastens the supplied mounting frame to the wall. Then the polycarbonate cover swings on the piano hinge to permit operation. As a result, the STI-6519 shields a single-gang switch or button while leaving it visible and operable.
What the STI STI-6519 is built for
Push buttons, smaller pull stations, keypads, electrical outlets, shutdown switches, and volume or lighting controls all sit on single-gang plates. However, exposed plates get bumped, jammed, or vandalized. Therefore, the STI-6519 places a clear, hinged polycarbonate barrier in front while staying see-through and accessible.

When the STI STI-6519 is the right choice
Specifically, the STI-6519 fits single-gang devices in high-traffic or vandal-prone areas. For example, classroom HVAC shutdowns, gymnasium light controls, and lobby intercom buttons. Also, the clear cover preserves visibility so the device is still easy to find.
Application context
The STI-6519 is a mechanical accessory and is not a UL-listed life-safety appliance. Therefore, mount it on top of the host device rather than substituting it for a listed cover. In addition, for tamper evidence add the optional STI-SUB-65 Break-Away Seal Kit.
