Shackles are mainly used to absorb tensile forces when transition from ropes, wire ropes or chains to solid components. The bolts are often secured with nuts or cotter pins. The use of a shackle makes it easier to replace a damaged wire rope or chain. Due to the curved shape, the connection is more flexible. Shaekels are often a cost-effective alternative to carabiner hooks, snap hooks and screw connectors. In the past, their use has proven itself in the following areas: Water sports, boat building, shipping, yacht construction, gardening and landscaping, food and beverage industry, water and waste water technology, mechanical and plant construction, conveyor technology, playground equipment, attachment of awnings and awnings.
