Note: Maco utilized this type of gearbox on their original door locks, but have subsequently (around mid 2010) upgraded the gearing mechanism. 5STK followed by a string of numbers was frequently imprinted on the gearbox label, and if yours has it, there’s a fair possibility it’s a match. A comparison of the detailed dimension graphic in our page listing, however, will be able to validate or deny this against your existing lock. The numbers after the 5STK refer to the type and combination of lock points and backset dimensions used by Maco. They are internal company batch codes, although they share the same gearbox, according to our listing.
