TenPoint has a complete line of crossbows. TenPoints String Dampening System (SDS) reduces string noise and movement with its cable-slot mounted string stop. The SDSs dampening rods feature high-impact rubber dampeners that work to diminish string vibration without affecting the speed or accuracy of your crossbow. The SDS is compatible with post-1999 TenPoint thumbhole-model crossbows, and includes hardware to adapt it to fit former 6 Point series and all Wicked Ridge crossbows.
