The ER-1374 Wire Manager delivers rugged, reliable cable management for hinged doors on trailers, trucks, ambulances, and specialty vehicles. Engineered to fasten directly into the door jamb, it stays securely in place—even during full rear-door swings up to 135°. With nearly double the internal space of typical wire guides, it easily handles more cables while maintaining a clean, professional look. Its unique design ensures quieter operation and smoother movement, making it the ideal upgrade for any application where durability and performance matter.
