Review on 🔌 WirthCo 20081 7-Way Trailer Plug Cover: Ultimate Protection for Your Trailer Connection by Srinivas Johnson

Picky mechanical engineer: This is a quality part. A very strong piece of polymer. Stretch the ring like a rubber band, plug it onto the 7-pin connector, it will shrink to its original size to hold trailer wiring in place. The protective cap then fits snugly over your 7 pin connector and the keyway fits the connector itself and protects your metal connections fairly well. There is also a clip that fits over the wire cable to hold the end cap in place while cruising down the road. If you look closely they even put small strain relief inserts into the T-joint where the ring bail meets the end cap body to strengthen the connection. QUALITATIVE.
