Scope. This handbook provides basic instructions for the
installation, operation, and maintenance of various mounted combination locks
and combination padlocks. Also included are detailed instructions for chang-
ing and setting combinations for hand-change and key-change combination locks
and combination padlocks. A list of locks included in this handbook is found
in Table 1, along with other pertinent information.
As noted in Table 1, not all of the locks are currently available
from the Defense Industrial Supply Center (DISC). However, those no longer
stocked were at one time procured in large quantities, and are included in
this military handbook. While the Sargent & Greenleaf 8500 Series and the
Mosler Models MRK 302-402 and MRK 120 were not distributed by DISC, they were
procured in large numbers direct from the manufacturers.
Purpose. This military handbook is for use by all personnel
responsible for the installation, operation, and maintenance of mounted
combination locks and combination padlocks.
