Durable Design and Protection

Every end of the air lines and ABS cables is guarded by stainless steel springs, delivering cushioning and resistance to everyday manipulation. The aluminum gladhand grips offer a durable, long‑lasting alternative to rubber components prone to wear. The red and blue air lines use a double-braided, three‑layer molding process, delivering higher burst pressure and improved resistance to twisting for a longer service life.

• Spring-protected ends reduce wear during installation and use
• Aluminum gladhand handles resist aging and damage
• 3‑layer molded hose with twist resistance enhances reliability

Power, Connectivity, and Storage

The 7‑way electrical cable uses a zinc die‑cast plug to efficiently transmit power from the engine to the trailer, with both ABS cable ends protected by springs for added cushioning. The gladhand holder keeps hoses and cords organized and secured, while tender springs buffer lines and cables during routing and setup. The tender springs are built from galvanized carbon steel with stainless steel clamps and rubber components designed for consistent performance under load.

• Spring cushioning helps protect connections during installation
• Holder provides organized storage and quick access
• Tender springs buffer and tidy lines for neat rig setups
