The Sears X-Cargo Carrier (known by the snail logo) is a classic, durable hard-shell car top storage box. Includes hardware and straps to attach the carrier to a vehicle with or without cross-bars. Used for some military PCS moves many years ago, otherwise stored inside ever since. The carrier is designed to attach two security locks (Locks not included). Holds 15 cubic feet of cargo, but if this is the larger model (?), it holds 18 cf. Good condition but could use a replacement of the foam weather stripping on the lid.
