Easy to use dampeners fit right in-between the split limbs with no tools or bow press required. They hold tight and will dampen vibration and noise on both vertical bows as well as many crossbows like the RavinTM Crossbow and others. These vibration dampeners are made of durable material that can be squeezed into tight limb gaps and stay in place. Use one on top and one on bottom, or you can stack them to make custom color set ups. Max limb gap: 1.20"
