Heavy duty BBHT Pacific Bay Tip Tops are perfect for use on heavy boat rods. Pacific Bay BBHT tip tops include Hialoy rings which are produced from a special blend of high grade Aluminum Oxide and are flanged for maximum strength. Because the Hialoy ring itself is diamond polished and permanently mounted to the black anodized stainless steel frame of the Pacific Bay BBHT, it results in lighter weight, greater heat dissipation, and decreased line wear.
