Not bad for the cost.

Super simple to install just drill one hole with correct size holesaw and attach with the included screws and boom dual outlets inside the trailer

I needed a simple way to put electric service into my metal shed. This plug worked perfect

5 ⭐️

Do yourself a favor and throw away the cheap screws the send with this.

I installed it on my 2000 Ford E350 van. Works great. But I need to seal the back somehow. Water can’t get in from the front. But it can get in from the back through the wire opening.

Very sturdy and durable design. Simple installation. Great for a shop or shed, RV, Trailer, or just anywhere you need a plug that you would like to keep waterproofed.

I have a shipping container on my property I use to store things, I wanted lights inside so I could see what I’m doing and this little pass through worked a treat. The construction seems good and It seems waterproof but time will tell, for now it’s exactly what I needed to complete the task at a good price.

These installed with Ease and I am very happy with the quality. They are built solid. Cap closes very tight.

I installed mine in the wall of a garden shed. Made it easy to power my shed with my solar generator.
