What is the purpose of an edge pad?

An edge pad serves primarily to create a barrier that separates the rope from a potentially damaging surface. By placing an edge pad between the rope and the edge of a ledge or other surface, you can prevent abrasion and wear on the rope that could lead to failure during a rescue operation. The material of the edge pad helps maintain the integrity of the rope, ensuring that it operates effectively under load and during dynamic movements. This protective function is critical in rope rescue scenarios, where the safety and reliability of the equipment play a vital role in the success of the operation.
