REPAIR OF BLACKOUT DOOR LOCKSPIN ASSEMBLY
The blackout lockpin is used to prevent the shelter door from being opened from the outside during blackout periods.
The chain mounted pin is located on the inside rear wall of the shelter to the left of the door. When in use, the pin
passes through a hole in the shelter door locking mechanism. (See fig. 14-1).
