Assembly Instructions Product Description These Zippy spacers designed for the BRS Alpha Beast 3.0 spacers are made in-house from a rubbery, shatter-proof polyurethane. They extend, round, and protect the handles of the AB, and offer a more neutral balance with adjustable tungsten weights. The adjustable weights allow you to adapt your Alpha Beast 3.0 to suit your specific balance preference, no matter what blade style you are running. Features Optionally extends handle length from 5.5" to 5.7". More neutral balance: Spacers are much lighter than stock spacers to reduce handle bias. Each spacer also houses up to 2x removable Tungsten weights for folks who prefer handle bias.. The weights can be popped out with a thin, rigid metal object using the 2 slits at the base of the handle extensions, and can be popped in easily with the tip of a clicky pen. Extensions round handles for a more comfortable ergonomic. Say goodbye to sharp edges at the end of the handles. Shatter-proof extensions protect your handles from hard drops. Positive jimping for extra grip on ladders and chokers. Each spacer weighs 0.073 oz empty, or up to 0.115 oz with 2x tungsten weights installed. For comparison, a stock Alpha Beast spacer weighs 0.123 oz. The full-length flush spacers each weigh 0.049 oz empty, or 0.091 oz with 2x weight Disclaimer The handle extensions were designed to fit flush with the Alpha Beast 3.0 "Thick Version," which has a blade thickness of 0.14" a total handle thickness of 0.503". This is the most common type of Alpha Beast 3.0. The Spacers will also fit the "Thin Version," which has a handle thickness of 0.478", but the handle extension will be about 0.02 inches (0.6 mm) thicker than the handles and will therefore not be perfectly flush.
