The use of SuperStacker Cribbing (composite cribbing) in applications where wood and lumber were used represents a commitment to certified safety that will outlast traditional wood cribbing 50 to 1. As it does not deteriorate, rot, splinter or fade, SuperStacker Cribbing is the safest choice when servicing or cribbing heavy duty OTR equipment. If your application requires markings or colors for safety, AME SuperStacker Cribbing can accommodate. SuperStacker blocks are designed to provide superior crib stability compared to standard hardwood and softwood products. They will not fail catastrophically like wood cribbing. In addition, unlike wood products, SuperStacker Cribbing blocks do not splinter or absorb fluids. Convenient sizes help to quickly and safely build stable cribs to support loads.
