If you have children, then you probably understand the importance of securing certain items. You don't want them getting into cabinets full of chemicals, tearing up valuables, or finding the family firearm. In most cases, you can attach a simple childproof device to keep the child from getting into trouble. However, some places require reinforcing with something a bit more durable. It is not difficult to attach a lock to something like a closet with double doors.

Place the key lock part of the hasp lock on the left door at an appropriate height and at about a 1/2 inch to 1 inch from the edge of the door on the right side, so that it is next to the gap between the two doors.
Mark screw holes on the door for the key-lock part and set it aside.
Drill holes into the door at the marks using a wood-drill bit appropriate for the size of your bolts. Keep the drill going into the door straight, so that the bolts easily slide through the lock and door.
Place the key-lock part back into position and slip the bolts through the attachment holes for the lock and into the holes in the door. Slip washers on the bolts on the inside of the door and screw on the nuts. Tighten the nuts with an adjustable wrench.
Place the latch side of the lock on the right door adjacent to the now-attached key lock part. Mark the drill holes with a pencil. The latch should overlap the other door, as the latch slips over the key-lock part on the other door.
Drill the holes for the latch part and attach with bolts just as you did with the key-lock part.
Fold the latch over the opposite door and slip it over the key-lock part of the unit. Slide the key into the lock portion and turn it. When the lock turns, it traps the latch under it and secures it in place. Store the key elsewhere.
