I installed this Frontline Defense astragal on the back entrance of a condominium. This door had been easily pried open by someone who then broke into several cars. This astragal has two interlocking parts.

An astragal protects the door edge from top to bottom. The door in the photo above provides access to a condominium roof and mechanical rooms.
