The B’Air Seal™ Door Guard is a revolutionary, auto-inflating door seal designed specifically for semi-truck cabs. When the cab doors close, the seal automatically inflates to create a tight, insulated barrier that blocks out wind, dust, water, and road noise. Built for durability and convenience, it enhances driver comfort, reduces cabin fatigue, and helps maintain a controlled interior environment in all weather conditions—without the need for manual adjustments.
