The G.E.N Weight Kit is a 1/2 ounce brass washer that fits into the spool of the G.E.N reels, allowing the angler to increase the weight of the reel by a 1/2 ounce. A rubber gasket is recessed into a groove in the washer's hole ensuring a snug fit on the spindle. A threaded hole in the weight allows for easy removal of the weight from a reel using the included weight removal tool. (See instructions here) G.E.N Weight Kits come with one 1/2 ounce weight and includes the weight removal tool.
