The KL-H Frame is the original KR Concept single -foot reduction guide. A game changer in
many respects, this guide satisfies all the theory embodied in the original KR Concept micro hypothesis.
A size 25 KL-H is over 6mm taller than a size 25 KL, offering fast choking performance
for small running guides down to size 4. Available in 13 sizes including a variety of medium
and low heights for perfectly tailored reduction trains.
