Built in Master Locks, what we need know to order the correct replacements

We sell quite a few Master Locks, and there are always a few items we are missing.   To order Master Locks we need to know the following:
1.  Which Model number are you looking for, here is our web page for your chooses.
2.  What is your Master Key #, this is found stamped on your Master Key, or you could be wanting a “new series”
3.  What is the School or Institution Name and Address, Master Lock keeps all the serial numbers  on file

If you only have a few Master Locks you would like to replace, we can do that also, all we would need to know is the serial numbers of the locks, which is on the back
