Just what I needed

I have magnetic lights on my horse trailer and the 12" extension wouldn't reach when a friend borrowed the trailer. This solved the problem and the quality is as good as the shorter extension purchased at the farm store.

Extensión resistente y funcional para remolque

Esta extensión de cable de 4 vías es justo lo que necesitaba para conectar mi remolque sin problemas. Los conectores encajan perfectamente y aseguran una buena transmisión eléctrica sin fallos. El cable es resistente al desgaste y la intemperie, ideal para uso en exteriores. La instalación fue sencilla y ahora tengo mayor flexibilidad al enganchar remolques. Es perfecto para los Remolques de U-Haul. Excelente calidad.
