Another method to protect the extension cords is by using plastic covers that you can make yourself. Just take the size of your extension cord and make a cover out of a plastic bottle for it.

It will be the least expensive but less durable. The steps of making a homemade plastic cover are:

  • Take an empty plastic bottle, rinse and dry it inside.
  • Cut a slit in the middle of the bottle horizontally.
  • Using your scissors, cut small holes on each side of the slit. The extension cord will pass through these holes.
  • Pass the wire through these holes.

Though this method is relatively very cheap and handy, it is unreliable in safety.

You can buy pallet wrap from a hardware store. This wrap is usually solid and reliable to ensure the protection of the outdoor extension cords from rain.

You will have to wrap the extension cord tightly with the pallet wrap so that it can withstand rain and moisture.

This pallet wrap can also be wrapped around your homemade plastic cover to ensure extra protection.

Another method to protect an extension cord is wrapping a plastic bag around it. Though this method is the least expensive, it is not preferable when you want a more reliable solution and doesn’t want it to look bad. 

5. Using a Duct tape

This method is very commonly used for extension cord protection from rain. The duct tape is water and moisture-resistant and is readily available from hardware stores.

This solution is not for long-term use, as duct tapes get damaged with time and extreme weather. 

6. Using a PVC pipe

Whichever method you choose, you need to follow instructions and preventive measures to avoid any electrical shock injuries or accidents.
