Fuji Guides NSG guides are light frame casting guides that are perfect for casting and light conventional rods that require flexible yet strong guides. They are stamped from one sheet of stainless steel and then anodized gunsmoke for strength, durability, and beauty. Fuji NSG guides utilize Silicone Carbide rings which is one of the most advanced ceramics made today. Diamond Polished SiC rings are mounted directly to the frames, which reduces weight, increases heat dissipation, and amplifies line sensitivity. Fuji NSG guides can be used with Fuji PST tops.
