The MTC-PC2 is a simple-to-use cover for the input terminal panel of many models of Control Contractor and Control Series loudspeakers. The MTC-PC2 installs over the existing input cup, provides a watertight gland-fitting entrance to seal and protect this section of the loudspeaker against incursion of water. The cover comes only in black. The cover section is paintable, but the gland nut is not. In order to seal correctly, the outside diameter of the cable MUST be between 0.170 inches (4.3 mm) and 0.470 inches (11.9 mm) and the cable should be jacketed externally with a round or near-round cross-sectional shape. Side-by-side "zip" type cables are not acceptable.
