Truck-Lite 50866 50 Series 7-Way Trailer Receptacle (Threaded Stacking Studs, 7 Solid Pin, Grey Plastic, Surface Mount)

Threaded Stacking Studs: Designed for high-efficiency wire management, the integrated stacking studs make it easy to anchor multiple electrical ring terminals without overcrowding the connection point.

Premium 7 Solid Pin Contacts: Features 7 cadmium-plated, solid brass pins that deliver superior conductivity. The "floating type" design allows the pins to align dynamically during plug-in, minimizing physical wear and maximizing service life.

Tough GE Noryl Plastic Housing: The heavy-duty grey body is molded from premium GE Noryl plastic, rendering it entirely non-conductive, high-impact resistant, and completely impervious to road salt, chemical washouts, and rust.

Eliminates Wire-Strand Breakage: Internal wiring relies on secure ring terminals rather than aggressive set screws. This intentional design prevents wire fraying and the subsequent resistance spikes that cause trailer lights to flicker.

Direct-Wired Internal Grounding: Eliminates intermittent chassis-ground faults with a dedicated, direct-wired internal ground path for absolute loop reliability.

Color-Coded Circuit Mapping: Embossed notation marks and industry-standard color coding are molded directly onto the housing shell to accelerate installation and simplify roadside diagnostics.

SAE J560 Standard Compliance: Built to standard commercial transportation dimensions to guarantee 100% universal compatibility with standard 7-way tractor-trailer plugs.
