This small shackle swivel has a hot-forged, CNC machined aluminium alloy body and high-tensile stainless steel axle. The Nexus 1 is part of a modular range with interchangeable components (this requires both 5/64" and 5/32" (2mm and 4mm) Allen keys, not included). This model comes supplied with one large bow shackle and one smaller D-shaped shackle. The removable shackles remove the need for a carabiner, though you can use them with these swivels. The large bow shackle allows for complex set ups to be achieved by catering for loading across the shackle. The D-shaped shackle give good stability when rigging from a single point.
