Protect your investment by not having your awning deploy while driving, or your house switch turn off with a fridge full of food, or your water pump turned on...These have all happened to someone. Plastic covers install easily with two or four screws (doubled-sided tape optional, but not provided). There are a number of different shapes available, depending on your model year and spec. Some customization can be done at home with a Dremel or file, just in case you have some mating hardware to clear. Made in San Diego, CA, USA, Earth.
