Normally, you’d find a string hanging from the cover of the stairway. For outside locations that might present a bit of a security issue. A quick pad lock will help secure the hatch. Done…unless there was NO string to pull!
Here’s a clever way to help prevent someone from easily opening the attic hatch door. (I’m not suggesting that you replace your padlocked stairway door, but this certainly is a clever way to prevent quick access.)
Attach a small hook by screwing it into the end of a wood dowel. Now simply store the handle in a secure place.
This also works great to help prevent the unsightly string from dangling in your hallway, should you be unfortunate enough to have a folding stairway inside your home.
