Attach two 1″ x 2″ x 42″ wood risers lengthwise, inboard of the edge and parallel to one another on top of the pallet deck. Lay the first row of seven keys over the risers. Lay the second row of seven in the opposite direction on top of the first continuing to stack keys in alternating rows until a total of seven layers of rows of seven keys have been placed on the pallet. Secure the keys to the pallet with two .75″ non-metallic bands over the top of the draft gear keys and under the pallet. Place a board or piece of plywood measuring 1″ x 12″ x 42″ on its edge on each side of the keys and secure with two .75″ non-metallic bands around the boards and the draft gear keys.
