Grote Industries has developed what it calls the industry’s first totally modular power delivery and lighting system, complete from trailer nose box to taillight. The Ultra-Blue-Seal harness system, paired with a new Ultra-Nose-Box receptacle and the company’s broad range of lighting products, provides an impressive trailer electrical and lighting platform.

The system minimizes wiring mistakes and downtime, while maximizing fleet and worker performance, says Grote.

The Ultra-Nose-Box is said to solve the problem of cracked, corroded and crowded electrical junction boxes. It features double the standard number of pin connections, a push-on plug function, a durable glass-filled nylon housing, insert-molded pins that seal out moisture and corrosive materials, and easily replaceable parts. There are also molded, threaded brass inserts that ensure the nose box is locked down, and a special mounting gasket that protects against moisture.

The modular Ultra-Blue-Seal (UBS) harness system is said to offer excellent connection sealing, configuration flexibility, and expansion capacity. The UBS connector system features patented double seal technology with dual sealing rings. Male pin lamp plugs, like those on Grote’s SuperNova line of LED lamps, are reinforced with banded terminals and a grease slot that keeps moisture out.

UBS is claimed to be flexible without being complex. The design allows for many types of connections without having to change the entire harness system. The system is easy to expand, because all the plugs use the same sealing technology.
