About this item

  • 【Ultra-Flexible Stretchable Design】This 4-pin trailer connector extender features a wire harness that can be stretched up to 2.3 feet (28 inches in normal), designed specifically to solve length limitation issues in trailer connections. Whether it's tight parking spaces or complex trailer combinations, it provides enough connection length for more flexible and freeing trailer connections.
  • 【High-Quality Materials & Precision Craftsmanship】Crafted with premium copper cores and thickened insulating jackets, it ensures excellent conductivity and durability. The plug section is precision-manufactured for perfect compatibility with trailer and vehicle electrical systems, reducing connection failures and safeguarding your driving safety.
  • 【Clear Markings for Easy Identification】To facilitate quick and accurate connections, we've labeled the plug and wire harness with clear wire function markings. This not only avoids potential safety hazards from misconnections but also boosts connection efficiency, making your trailer connections simpler and clearer.
  • 【Wide Compatibility】With a universal 4-pin design, it is compatible with most trailers and vehicle electrical systems on the market. Whether for family outings, outdoor adventures, or commercial transportation, this extender will be your indispensable helper.
  • 【 Portable Storage & Space-Saving】The unique stretchable design not only facilitates use but also easy storage. When not needed for extension, the wire harness can be easily contracted to a compact state, saving space in your vehicle and trailer for a neater and more organized travel experience.

I needed an extension for an atv trailer with short wires. This is nice and heavy duty, the curls in it keeps it the right length and I don't have to worry about it dragging on the ground. Great purchase
