Entry Door

McMason combo door, which is also called mobile home combination door, is a two-in-one door unit. It is made up of the main front door with a storm door. The reason homeowners purchase these types of doors is due to the security that the main door provides, which seals off the home and prevents drafts from entering, similar to windows. The storm door, or secondary door, then acts as a double barrier. Storm doors allow sunlight and fresh air into the house while being locked shut.
