master lock numbers?

[echohtp]

hey ive been looking around the forums and i havnt seen anything about the numbers on the bottom of master locks anyone have some information on these or a site i could refer to?

The Master website has a whole bunch of information on each numbered lock, and there is a great deal of information here on these locksas well. For example, the 1,3,5,6 (and a bunch more) locks all use the same cylinder.
