Extremely durable, Pacific Bay Guides CSBBG Guides guides feature stainless steel frames and groove-resistant tungsten carbide alloy rings. Their amazing resistance to the corrosive effect of saltwater makes them an ideal choice for offshore boat rods. In addition, Pacific Bay CSBBG Guides will readily withstand the continual back and forth abrasion found in downrigger and wire line trolling situations. A center support bridge is included for additional strength, and all welds are silver solder reinforced.
