Universal Stopper Cover for safety devices

The STI-13020NY is a clear polycarbonate cover designed to protect dual-action pull stations, emergency buttons, keypads and similar wall-mounted devices. It fits indoor and outdoor installations where vandalism or accidental damage is a concern. The cover meets ADA requirements and carries UL and cUL listings for code compliance.

IP56 rating and -20 to 120 °F operating range

The polycarbonate housing seals to IP56, keeping out dust and powerful water jets during wash-downs or storms. It remains stable from -20 °F to 120 °F without warping or becoming brittle. No moving parts or powered components mean zero noise and no power draw in normal use.

Surface-mount design frees the device underneath

The cover mounts directly on the same surface as the protected device, adding only its own low profile without requiring extra back-box depth. Clear material leaves indicator lights and labels fully visible while the hinged lid stays open for testing or reset. It accepts the mounting hardware already used by the pull station, switch or keypad.

Questions about this item

How is the STI-13020NY Universal Stopper Cover mounted, and what step do installers often miss?

Mount the clear polycarbonate cover over the target device — dual-action pull station, duplex plug, light switch, emergency button, intercom or keypad — using the supplied hardware on a flat surface; the step often missed is verifying the gasket seats evenly so the IP56 seal holds against water jets.

What maintenance or replacement will the STI-13020NY need over time?

Inspect the polycarbonate cover and gasket periodically for UV yellowing, cracks or compression set; replace the cover if clarity is lost or the seal no longer meets IP56, and check that the ADA-compliant operating force remains within spec after any impact.

What is the first limit the STI-13020NY hits under sustained outdoor exposure?

The operating temperature ceiling of 120 °F is the first hard limit; prolonged exposure above that temperature can deform the polycarbonate and compromise the IP56 rating before any other spec is reached.
