Elsie Altenwerth
Much improved setup

This plug/junction box significantly improved the wiring setup on my 16 ft. equipment trailer. Easy to mount, easy to hook up and works great. Great value, highly recommended.

Valentina Zieme
Works as designed.

The plug head seems to be sturdy and fits snugly into the receiver. The wiring box has plenty of space to tuck extra length. Connected everything just as the instructions say and it worked perfectly. Even has painted on color coding on the wiring bolt and nut. The wire looks to be much heavier Guage than would be needed but is very flexible still. Nothing at all negative. Just a well built piece.

I have used three of these on three different trailers. They always work perfectly and seal out the elements perfectly. Good product.
