The QC Ring Round swivel has been specifically designed for chod rigs but is compatible with any other type of rig where a rigid boom material ends with a ring. Instead of a traditional swivel eye, this model features a rounded hook on which to thread a tied or crimped loop. This allows you to change the rig style used during the fishing session with a helicopter rig setup without needing additional sleeves. This hook is designed for use with thicker terminal materials, such as Boom and Mouth Trap, as they fit perfectly without the risk of the hook detaching during a fight. The only time the loop can come off is when you change the terminal. Size 11, these swivels are perfect for use with a helicopter rig (with the ring threaded either on the leader or directly on the mainline in a naked setup) and create a very neat final result. They are sold in packs of eight pieces with a matte PTFE coating.
