Modern Black Steel Double Door

The security measures at the Air 4 building are better than what the industry requires. They use strong 12-gauge materials, a 2-inch thick door, steel thresholds, and bullet hinges to improve security. Also, users can easily install the door because of pre-drilled tabs.The Air 4 model comes with protective features such as 5/8 inch tempered dual pane glass, Polyurethane dual foam weather stripping, and a door sweep at the bottom. These features work together to keep out drafts, insects, smoke, moisture, noise, light, and fire from entering your room.
