NA14 / 1069L National 4-Pin Cabinet Key - Brass (JMA-NTC-1DE)

Having used almost every brand of key blanks in the last 46 years, I have found that some companies don't make their products consistently. Ilco had a run of problems with KW-1 for a while as they would not fit some KW-1 Copy locks (SNAP IN DEADBOLT, RELIABILT, EZSET, ETC.) This will not be the same with JMA. Like Star Blanks from the past, they are thinner that ILCO blanks which can be a plus with locks from CHINA. Some blanks like DE6 and Y-1 have undersized heads. The NA14 will fit in MAILBOX LOCKS from co's other than National Cabinet locks and can be a plus. Hope this gives you food for thought.
