A lightweight and flexible load bearing shackle that is configurable in operation. The shackle includes a bow made of a plurality of loops of synthetic fiber rope (e.g., polypropylene, nylon, polyester, polyethylene, Aramid, acrylic, mixtures of several fibers, co-polymer fibers, straight, braided, twisted). The loops of fiber rope may be contained within a sheathing configured as a single loop. The sheathing is secured together to form a receptacle (opening) in each leg of the bow that is reinforced with an eyelet. The eyelets may be split eyelets that include a first/second side mounted to a first/second side of the receptacle that are then secured together over the receptacle. A connection pin may be secured between the eyelets. The shackle may include a spacing mechanism (e.g., casing that connection pin traverses, connection pin that has wider center portion) between the legs to maintain the legs a certain distance apart.
