KT Runners are available in sizes to cover micro-rods, KR Concept and conventional layouts using NGC. It is the “standard” K-Series runner used in every K-Series layout and provides excellent strength and tangle-free performance. Beginning at size 6, KT has sufficient foot profile to be used as a mid-rod “stress” guide so there is no need for KB belly guides on layouts with runners size 6 or larger. Dark grey with Alconite ring. Model BCKTAG.
