Fuji Single Foot Running Guide - Corrosion Control frame - Fazlite ring 

K-Series guide trains of all kinds have a few things in common. The specialized KB Guide, for example, is used as the choke point guide and mid-section casting guide in every K-Series guide train specified. And, all KB’s are followed by the standard KT running guide, a strong, lightweight guide that pairs perfectly with other K-Series. The KB and KT are listed here, and will be repeated as guides used in KR Concept rods as well.

KT Runners are available in sizes to cover micro-rod and conventional layouts using NGC. It is the "standard" K-Series runner used in almost every K-Series layout and provides excellent strength and tangle-free performance.
