Slings are flexible and sturdy closed textile straps. They can take a lot of weight and are available in different lengths. This makes them perfectly suited as anchor points for fall protection or hoisting. Slings are usually made of polyester, but you can also choose extra abrasion-resistant Dyneema or lightweight material. There are some things you need to know when working with slings, though. For instance, the load capacity of a sling depends on how you use it.
