The Stowaway 20-20 ATA Shipping Case comes with full lining and pluck foam. It is designed to meet the recommended ATA 300 specifications for airline shipping cases. It is constructed of lightweight but tough Mil-Spec HDPE (high density polyethylene plastic) with aluminum valance, industrial heavy duty twist latches, 3 spring loaded side loop handles, and lid stays with pluck foam on the inside. See the high quality adjustable divider sysem available for this case that allow you to reconfigure the interior for a variety of equipment uses when circumstaces require. We also have a TSA pad lock accessory. This lightweight shipping case with foam only weighs about 16 pounds and leaves room for about 34 pounds of cargo payload before the airlines 50 pound weight limit is reached. In short, you can carry a bigger payload inside a Stowaway 20-20 shipping case.
