The LT-4000 is a wall and ceiling access door made of lightweight aluminum. Thanks to a sturdy design and lightweight components, access to considerable gaps in walls and ceilings are simple. The mitered metal frame has a beautiful architectural look. The manufacturer uses 3/4" polystyrene insulation to line the metal door panel. The LT-4000's all-aluminum structure is perfect for outdoor and interior applications where corrosion or moisture is a concern. It uses 1/8" x 3/8" closed cell neoprene gasketing between the door and the frame. There are no tests conducted to see if it's airtight or waterproof.
