Product Description These HOM Prodigy Mod C spacers are made in-house from a rubbery, shatter-proof polyurethane. They extend, round, and protect the handles of the Prodigy, and reduce the weight by 0.076 oz for a less handle-biased balance profile. Assembly Instructions Remove the stock spacers and insert the Zippy spacer. While applying inward force pushing the spacer into the handle, push the sexbolt into the spacer holes. You will need to push the spacer firmly in to the handle while pushing the handle down onto the sexbolt to ensure the holes line up. Positive pressure is necessary. Some wiggling of the top scale will likely be necessary; you may need to "pull" the top scale slightly toward the spacer to achieve proper alignment. Once the sexbolt is successfully through both scales, tighten down the spacer body screw until you feel a light resistance. Next use the stock spacer as a guide to the thickness by wedging it in the channel below the Zippy spacer and tightening the handles until they press upon the stock spacer; then remove the stock spacer. Features Extends handle length from 5.375" to 5.67" Positive jimping for extra grip on ladders and chokers. Shatter-proof extensions protect your handles from hard drops. Rounds handles for more comfortable ergonomic: say goodbye to sharp edges at the end of the handles. Unweighted Zippy spacers feature a lighter weight with reduced handle bias: 1x Zippy spacer weighs 0.040 oz. For comparison, 1x stock Prodigy Mod C spacer weighs 0.057 oz. Since the Zippy spacers are used with only 1 body sexbolt (instead of the 2 stock sexbolts), the total weight reduction for a set of 2 spacers amounts to 0.070 oz, reducing the handle bias of the Prodigy Mod C. The Prodigy Mod C with the Zippy spacers weighs 4.450 oz, down from 4.532 oz. Optional weighted Zippy spacers provide adjustable weight system: each weighted Zippy spacer weighs 0.048 oz (empty), 0.069 oz (1 weight), up to 0.091 oz (2 weights) for those who want more end-weight and handle bias.
