Understanding how rigging ratings work helps you pick the right equipment for a heavy load. Each item has a maximum safe working load, and the 25,000-pound capacity is associated with the heavier-duty option in this set. The MB-2 Chain & Device is the higher-capacity assembly designed for that level of load, making it the correct choice for a 25,000-lb requirement. The MB-1 Chain & Device is lighter and carries a smaller rating, the CGU-1/B cargo strap is a strap with a much lower working load limit, and Approach Shoring is a structural support used to distribute weight rather than a chain-and-device rated for 25,000 pounds. So, the MB-2 Chain & Device is the item with a 25,000-lb capacity.
