Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

PRODUCT OVERVIEW:

Streamline and protect your entire towing electrical system with this professional commercial-grade 7-pole weatherproof ABS junction box assembly manufactured by Jammy Incorporated. This heavy-duty system comes pre-wired directly to a 6-foot long 7-way RV cable, featuring a molded 7-way flat pin blade-style trailer plug engineered with single flat pin contacts, which is the only officially SAE J2863 accepted configuration type. Built to facilitate clean wiring layouts, the heavy-duty multi-conductor cable comes pre-terminated with crimped and soldered insulated ring terminals, which are securely affixed to an internal bus bar per standard RV color coding. The internal bus bar is permanently secured to the robust box body with durable rivets, and the package supplies additional clamps and open grommets to complete a secure setup. Designed to survive extreme transit environments, the premium GPT-shielded multi-core cable is strictly rated to withstand temperatures ranging from -10°C up to 105°C. Complete with integrated hang holes to prevent the molded plug from dragging on the highway or getting dirty, this top-tier electrical nerve center from Jammy Incorporated mounts cleanly on 7.35-inch centers to ensure ultimate long-term circuit protection for your commercial trailer fleet.
