All of the ProSeries® locks have a generic construction technology that allows for a uniform assembly and disassembly technique.
Two functions are available in the locks, NKR (Non Key Retaining) and NRK (Non Removable Key) and both functions are accomplished as a design feature of the extension.
Master Lock Company makes seven basic cylinder sizes/types for use in our padlocks. All locks are supplied with a six pin length cylinder for uniform keying capability. The cylinder may be combinated with 4, 5, or 6 pins to accommodate existing key codes.
Master Lock keys are coded from bow to tip and with a few exceptions, the increment used is .0155". Master Lock keys will be encountered with two types of stamping on them. Both direct and blind codes are stamped on the keys for different products.
All the locks use an extension mechanism that causes the ball bearings to lock or unlock the shackle. Typically, these locks are supplied with a non key retaining function extension.
