The foam in the lid is glued in and the foam in the base (which is protected from the feet of the tripod by a plastic disk) is held in place by detents that are molded into the base of each case. The case is carried by a molded-in handle.The case is carried by a molded in handle and transported by built-in 2.0" recessed wheels.
