Cut a wood block that is 1/2-by-3/4-by-2-inches.
Drill a hole in the block that is centered and 1/2 inch from one end.
Screw the block to the rear of the drawer so that 1/2 inch of the block is above the back board of the drawer. Tighten the screw enough that the block stays in place but loose enough for you to turn the block horizontally with your fingers.
Slide the drawer into the cabinet or chest with the block horizontal. Reach into the drawer and turn the block vertical. This will block the drawer from pulling out.
Things You Will Need
- 1/2-by-3/4-by-2-inch wood piece
- Add stop blocks to all of your drawers that pull out too far. This will protect people from being injured by falling drawers.
