Optronics has been named the master distributor for Connect-to-Protect Trailer Harness Plug Protectors. The protectors enable users to shield the male end of a trailer's harness plug when it's not in use. It comes in two configurations that accommodate 95% of all light- and medium-duty harness connectors, including 4-way flat, 5-way flat, and 7-way round terminal styles.

Wiring harnesses on trailers are vulnerable to corrosion and the root cause is moisture intrusion. In addition, corrosion-causing moisture and chemicals most often find their way into a trailer’s electrical system through the connection points in its cabling. Connect-to-Protect Brand Trailer Harness Plug Protectors are designed to help guard a trailer’s electrical system by protecting the integrity of the wiring harness at its connection point. The product’s protective female receptacles effectively seal the trailer’s connectors against damage, shielding the plug, terminals and wiring from moisture, dust, abrasion and the resulting corrosion.

The plug protectors are installed on the trailer’s hitch coupler arm to shield the male harness plug and keep it from dragging on the ground. Fasteners are included, so the only tools needed for surface mounting are a drill and a screwdriver. Flat versions mount with a single screw, and the round version uses four. Each screw requires a 0.125-inch pilot hole.

The product is manufactured using a rugged PVC material that remains durable, flexible and resilient, even in extreme weather conditions. It is covered by a three-year warranty.
