Stabilize your shipment with poly-woven airbags. These products are perfect for filling any gaps between your pallets, barrels, crates, and other cargo. Simply place and inflate to prevent unwanted movement and/or damage. They also provide shock absorption for extra security. Constructed with a two-way locking valve, it's quick and easy to inflate and deflate these air bags. The typical fill time is less than 30 seconds! They can be used in road trucks, intermodal rail cars, boxcar rail cars, and overseas containers. The recommended void width for most applications is 0-14 inches, but for intermodal rail cars, it's 0-12 inches.
