Ensure the safety of your freight and rail workers with Labelmaster’s Rail Chocks. These OSHA-compliant single and double chocks stop freight cars and locomotives from moving, making them safe to load, unload and repair. They are made of heavy duty, cast steel that is designed to stand up to heavy rail car loads on exposed and flush rails. Heat-treated spurs bite into rails to keep chocks from slipping. OSHA-required rail chock accessories are also available. There's no need to worry about rail car movement that could injure your workers or cause damage to valuable freight with these simple but necessary rail car wedges.
