The Dark Matter Balancing Weights are the perfect solution when fishing waters that contain crayfish as they can not pull them off the rig. They will fit over ALL Korda size 11 swivels-we have done everything we can to try and control the tolerance of Korda size11 swivel barrels, but sometimes they are a little tight to push on fully by hand. We recommend using a Krimp Tool to carefully bring the balancing weight and swivel together. Please note that they will not necessarily fit on competitors size 11 swivels, as sizes vary. Tungsten is a very hard material it has little flex and therefore can not be easily forced on to oversized barrels.
