Our cast steel railcar wheel chocks have heat-treated spurs to prevent slipping. To extend product life, they can be turned to provide three new, sharp edges, and they can also be easily replaced. OSHA railcar regulations require that a wheel chock be in place before a train’s railcar can be safely worked on, and our wheel chocks are designed to meet those requirements, including OSHA regulations 1910.110(15), 1910.11(13) and 1910.110(A) (5).
