Replacement Archery Bowstring for Traditional Recurve Bows - Available in AMO Lengths from 44"-68" in 12, 14, 16 Strand - Made from Black Dacron B-55 Material NEW B-55 DACRON MATERIAL  This high quality string is made in the USA out of 100% polyester and has many of the same qualities as Dacron but offers superior durability while allowing very minimal stretch over time ensuring that you get the most life out of your string! AMO LENGTH vs ACTUAL LENGTH  To help guarantee you select the correct string for your bow, keep in mind that AMO length refers to the bows overall length and the strings actual length is approx. four inches shorter than overall bow length. SELECTING STRAND COUNT  We recommend choosing a specific strand count depending on the draw weight of your bow. The heavier the poundage bow, the more strands required to prevent stretch and maintain the string length over time. EASY INSTALLATION  Center serving and both loops are pre-served making these strings ready to install immediately! Dont forget to a stringer tool when installing your string to make certain both you and your bow are as safe as possible.
