How to Construct a Primitive Door Lock

Primitive door latches are usually sliding bolts or hooks that have no internal mechanical parts like a standard lock would. These locks are useful for shed doors, fences, inside doors and doors that have only one way to go through. Constructing a primitive door lock is not a difficult task. It can be done with basic tools and just a small amount of time. A barrel bolt latch is a common example of a primitive lock.
