This MECMO 60-inch (stretchable to 5ft) 4-wire flat extension uses a coiled design and durable materials to bridge gaps between mismatched plugs or to give extra slack without creating a trailing hazard. It’s suitable for common trailer types including boat, ATV, motorcycle, horse and cargo trailers that use the industry-standard 4-way flat connector.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the coiled design reduce cable drag and tangles?\u003c\/h3\u003e\n\u003cp\u003eThe spiral, retractable cable stays compact when not stretched, keeping the wiring off the road and out of harm’s way.
