What is the purpose of the steel strap in the fall arrester?

There is a very important part in the high-altitude fall arrester-steel belt. The steel strap is located inside the fall arrester housing and is used as a gasket. The steel belt is a circle-like part made of high-quality steel. It is of suitable thickness, hard material, light weight, strong bearing capacity, and will not be easily broken. The manufacturer also plated a layer of zinc on the outside of the steel strip, which can prevent the steel strip from being corroded by air and moisture and rusting.
