This unique and patented device has helped prevent theft and vandalism to access controls, digital keypads, push buttons, smaller manual pull stations and much more around the world for over 30 years, without restricting access to protected device.
The STI 6535-B is a protective cover for surface mount devices (flush - see STI 6525-B) that consists of a clear, tamperproof, super tough polycarbonate cover, weather gaskets, frame and blue conduit spacer. Cover contains no horn. Additional models (indoor only) are available with a built-in warning horn that sounds when the cover is lifted to gain access to the protected device (see STI 6605-B).
This tough UV-stabilized cover helps extend the life and reliability of weather exposed devices and also guards against damage from dirt, grime and other harsh indoor conditions. STI 6535-B is especially useful in increasing the lifespan of devices in saltwater areas or other severe environments.
