There is a much better way to solve this problem. In this case, flip-up covers are a great option for installing extension cords to an outside outlet.
These covers are designed with a deep lid and grooves in the bottom of the lid so that extension cords can run out the bottom of the lid without having the lid open, exposing the outlet to the weather. These plastic covers are pretty durable and usually come in a clear or smoke-colored lid.
There are many different types of boxes on the market, but they are divided into two simple categories:
For new installation, like in new homes.
For remodels.
