Take the guesswork out of picking with the Peterson I-Core Tension Tool! These specially designed tools enable you to pick the cylinder of a small format inter-change-able core (SFIC) open at the control pin shear line. From there the core can be cleanly removed from its housing. The secret is in the profiled foot that firmly grasps the holes in the control sleeve. Put the tension where you need it! Can be used with Arrow, Best, Falcon, Ilco, KSP, Schlage & Master Small Format I-Cores. Patterned after the original Gerry Finch tool, this is our medium thickness I-Core Tension tool. Proven to work the best on D, B, E, F, G, H, K, and N keyways.
