Abstract

In one or more arrangements, a stackable pad system is provided. The system has a plurality of blocks with each block having a flat upper surface with an upward extending lip positioned at opposing ends of the flat upper surface. Each block has a flat lower surface with a downward extending lip positioned at opposing ends of the flat lower surface. In some arrangements, the system includes a bottom locking plate and a top locking plate. When placed together, in a stacked arrangement, wherein a bottom most pair of blocks are stacked on top of the bottom locking plate with bottom lips fitting within the recesses of the bottom locking plate, additional pairs of blocks are stacked on the first pair of blocks and the top locking plate placed on the top most pair blocks, the blocks are all locked together and resist shifting and movement.
