A palletized load cover is disclosed. The cover includes at least one elastic strap which is held captive on the cover. Integral connectors are provided on each end of the strap and the connectors cooperate with a conventional pallet including at least two retractable belts which can be locked against further unwinding when unwound. Guides are provided on the cover to restrict lateral movement of the strap while permitting limited longitudinal movement of the strap. The connectors provided on each end of the elastic strap are operable to releasably lock with cooperating connectors provided on distal ends of the pallet belts. With the belt connectors locked to the strap connectors at each end of the strap, the belts are pulled so that the belt retracts and is locked against unwinding. The elasticity of the strap makes it possible, with conventional belt retractor mechanisms, to achieve an unprecedented level of strap tightness, thereby making a palletized load secured with a cover according to the invention significantly more secure than has been possible with prior art load covers. In addition, the strap connects belts from opposed sides of the pallet and maintains or restores equal tension in the two belts, continuously. In one embodiment, a single elastic strap, in the form of a closed loop, is provided on the cover and it is operable to equalize tension in four pallet belts secured to it.
