With the purpose of protecting the clocks within your system, Valcom's Wire Guards are designed for use with 12-inch and 16-inch round analog clocks. Each Wire Guard is fabricated from 3 gauge steel rods, which are welded together and have a zinc-plated, lacquered-baked clear coat finish. These heavy-duty Wire Guards come complete with fixed tabs welded to the rods for mounting directly to the wall. They are hung completely independent of the clock in order to provide maximum protection.
