The Universal Stopper
This 4-inch polycarbonate cover
provides excellent protection for indoor/outdoor devices, including
keypads, switches, and dual-action pull stations. It protects against
accidental and intentional damage, dust and grime, and severe
environments. The unit doesn't interfere with operation and can be
flush- or surface-mount, or supplied in a waterproof backbox.
