Aluminum mortised air door sweep. 43" long. Legacy part 7183MA.
This option allows free flow of air while still blocking light at the bottom of the door. Useful for applications with pressure differentials, such as boiler room doors, it is also a practical solution for certain hotel room and stairwell applications. Our AIR design features double rows of notched and staggered neoprene seals for effective air flow.
