Fuji Guides BNLG guides are light frame casting guides that are perfect for casting and light conventional rods that require a flexible yet strong guide. They are stamped from one sheet of stainless steel and then anodized black for strength, durability, and beauty. Fuji BNLG guides also feature Hardloy rings which are produced from a special blend of high grade Aluminum Oxide. Because Hardloy rings are diamond polished and permanently mounted to the frame, they result in lighter weight, greater heat dissipation and decreased line wear. Fuji BNLG guides can be used with Fuji BPLT tops.
