Pop Up Weights Description Fox Edges Kwik Change Weights provide the angler with a multitude of balancing and weighting options. Ideal for popups. Available in four popular, practical sizes to cover a variety of uses. Very useful where crayfish are present where putty will be removed in seconds. The weights are attached simply by placing your hooklink into the slot and stretching a piece of the rubber section to make its cross section thinner then placing into the slot releasing the tension for elastic to expand to normal size and apply grip. Putty can be applied over the weight if further counterbalancing is needed. Fitting Tip. Dont cut off a section, simply fit elastic to weight and then trim off of spool before trimming both ends of weight to neaten it up. This forms a totally secure fixture that will not damage the line. Weight can be removed for reuse. We have feedback that there is no rubber in the container. It is well hidden and you need to pry the green case down with your fingernails while pressing up on the base centre. This will reveal the elastic coiled around the container. See image.
