Abstract: A cargo restraint device is automatically adapatable for the retention and conveyance of half size width or full size width pallets and containers on a floor mounted track in a vehicle such as an aircraft. A pair of similar wing portions are spring urged to an upright position opposite each other. Each of the wing portions has an arm which extends outwardly therefrom from a support plate in a direction substantially normal to the support plate, these wing portions being adapted to engage the edges of the pallets or containers to retain them to the track. A camming member has a camming arm which engages camming surfaces on the wing members. This camming member is spring urged upwardly so that the camming arm thereof firmly engages the camming surfaces of the wing members at all times.
