Grote 67271 24” Cut-To-Fit® Rear Sill Adapter – Jumper Harness for Ultra-Blue-Seal® Systems

The Grote 67271 is a 24-inch (2-foot) jumper harness designed specifically for the Cut-To-Fit® Wire Harness System. This rear sill adapter provides a critical bridge between the main trailer harness and the rear sill lighting distribution. Engineered for heavy-duty performance, it is the primary solution for technicians needing to adapt or repair Grote's modular systems while maintaining a high-integrity electrical circuit.

In the harsh environment at the rear of a trailer, road spray and chemical de-icers can quickly destroy electrical terminals. The Grote 67271 is designed to plug directly into elbow-style rear sills, utilizing Ultra-Blue-Seal® (UBS) technology to create a completely corrosion-proof connection. This factory-molded, sealed interface blocks moisture from wicking into the wiring, significantly reducing the maintenance costs associated with lighting failures.

Built to handle the power demands of modern trailer lighting, the 67271 is constructed with premium 14-gauge GPT wire. It features a Slim-Line .180" Male Bullet on one end and a Double Slim-Line .180" Female Bullet on the other. This "plug-and-play" versatility allows it to mate seamlessly with the Grote 7-pin nose box (when used with the 67260 or 67250 adapters) or plug directly into double slim-line plugs within the main harness.
