OTU mode is great for day use
lockers whereby each person that walks up to an open locker enters their
own code and use that same code to open. Optional standard mode (w/ a
flip of switch on back) would be just one static combination.
Manager key overrides
combination and allows code discovery and lock can be set to a new
combination. One key controls all locks in the group.
No matter what size the
tool, this combination locker lock resists attacks to the knob with a
ratcheting style knob that rotates when forced.
The most competitive
pricing on an all metal combination lock with key override with many of
the more advanced features of locks (but minus the batteries!)
