Which of the following has a rated capacity of 4,420 lbs?

The 5/8 inch screw pin clevis has a rated capacity of 4,420 pounds, making it a critical piece of equipment for safely securing loads during air transport operations. This component is widely used in various lifting and rigging applications, which require strong yet reliable fastening methods. Its design allows for easy attachment and detachment, fulfilling the functional requirements of a pathfinder. The rated capacity indicates its strength and reliability for supporting substantial loads under operational conditions.

In contrast, the other options represent equipment with higher rated capacities or different functionalities. The apex fittings and sling legs mentioned carry a significantly larger load-bearing capacity, suitable for heavy load operations, while the grabhook assembly also serves specific purposes that may not align with the 4,420 lb rating associated with the screw pin clevis. Understanding the specific capacities of these components is essential for ensuring safety and effectiveness in airborne operations.
