How to Lock a Bulkhead Door

Installing a lock on a basement bulkhead door is an important step in home security. While a padlock on the inside or outside of the door may suffice for an outbuilding, in an emergency you can't risk being trapped in a locked basement. On the other hand, leaving the bulkhead door unlocked is an open invitation to thieves. Installing a bulkhead or cellar door lock requires a drill, drill bits for use with metal and basic household tools.
