This Fusion Climb FP-8300-BLK Delta Swivel is made from a high-density aluminum alloy. This allows for a lightweight nature yet strong capacity. The swivel is one of the most fundamental pieces of equipment that is used to prevent rope from becoming tanged and twisted. These Delta swivels are a rotational climbing device often used to prevent tangling of lines in climbing applications or lifting loads. Great for positioning systems while maintaining a full 360-degree range of motion provided by the enclosed stainless steel ball bearings. Both Delta rings on either side of the swivel allows for bulky attachment with a maintained stability. All Fusion Climb hardware are TAA Approved.
