Revelations 4 pack fits the 11/16" gap. These dampeners fit the Hoyt, Bowtech, Tenpoint, Parker Crossbows, Barnett, and Carbon Express crossbow models. Some older model Bowtech's have 1 1/8" gap these won't fit those models and won't fit on the Bowtech solid limb models.269 grains each. When installing these dampeners it's best to keep 2 on the top side by side, and the 2 on the lower limb side by side. This will prevent them from sliding and moving.
