These Frames are stub ducts that adapt SHX pressure vents, and Dynamic weather louvre, into thin walls, doors and cladding. They facilitate surface mounting of pressure vents inside containers or other thin walls, and provide weatherproof cover boxes for protruding vent bodies. They also allow neat installation of Dynamic weather louvre onto exterior building cladding.
