Gas Locker

I bought a new lock for the Gas Locker Door because the old one was a bit old and the cover disappeared.  Today I took the old one off and installed the new one.

I noticed a few years ago, after I had purchased it, that the outer lock assembly could freely spin.  So, someone could just grab it, spin it anti-clockwise, and the door would open.

While installing the new one, I decided to investigate.  There are 2 screws on the inside assembly.  Aha...their purpose is to prevent the outer assembly from spinning!!  Um.....the screws were about 1 cm long.    The locker door is about 3 cm deep.  Grabbed a couple 4 cm screws and used them.

Problem solved!  I cannot believe that it was built that way.  Has anyone else had this problem?
