Master Lock has always been confusing with the 379. Years ago, the KA and KD versions had the same body style, but different coatings, and now they have replaced the KD version with this totally new style, but kept the old style for the keyed-alike / rekeyable version. In any case, the Master 379 in either version is still a great economical little universal coupler lock.
