Ashima ronny rig swivels are made of High Tensile black coated steel. Due to the matte black color, the cable glands are minimal under water. Ashima Ronny rig swivels have a pull of 25 lbs. Due to our unique diameter of the swivel, it fits almost all hooks from size 4 to 10. These swivels are also very suitable for a so-called hinged “Adjustable” ronny rig. The thin diameter allows the swivel to move freely in the eye of the hook.
