Rated 4.8 out of 5 stars.
Facility managers and locksmiths—this one's for you. It's a BEST 1C7F1626 interchangeable core, open box but in excellent shape. Keyway is Type F, 7 pins, made from solid steel. Length is 1.25 inches, depth 2.000. This is the kind of core you use in commercial door systems where you need to rekey quickly without pulling the whole lock. No batteries, no cables—just good old-fashioned mechanical reliability.
