Can be used on their own or as part of a system with the Quick Release Method Mould. The flat-bottomed design makes them ideal for all situations, including casting tight to the sloping banks of an island. The recess in the front of the feeder accepts a size 10 swivel, which will provide just enough tension to make a semi-fixed rig. Alternatively they can be used with Korum Quickchange Beads to make a completely free-running rig.
