    Plug Extension
  

*by B***R on Reviewed in the United States on March 20, 2024*

It is hard to see in the picture but the extension plug is hanging.This is to allow the warm air to soften the plastic and take it from being coiled up to a straight wire.This will make for an easier and cleaner look when using the extension.In the second picture I have a light strip that goes on the back of a scooter carrier on a motorhome.The wiring on the strip is not long enough to connect to the trailer plug.This extension will easily get from the end of the strip wiring to the trailer wiring.This is good quality wire and then ends are very tight.
