Ultimate Protection for Trailer Electrical Connections

The Grote 87141 Ultra Nose Box® is the professional choice for protecting critical tractor-to-trailer electrical interfaces.

Advanced Corrosion Resistance and Durability

Built with Grote’s commitment to longevity, the 87141 is constructed from high-impact, non-corrosive materials.

Its robust design ensures that internal wire terminations stay clean and dry, significantly reducing the risk of intermittent electrical shorts and downtime caused by terminal corrosion.

This Ultra Nose Box® is designed for easy installation and long-term serviceability. The spacious interior allows for clean wire management and secure routing of heavy-gauge cables. Whether outfitting a new trailer or replacing a worn-out socket housing, the Grote 87141 delivers a permanent, weather-tight solution that keeps your fleet compliant and your lights powered.
