No
closet offers the security of a burglar or fire resistant safe.
However, you can beef one up to protect valuables against
grab-it-and-run thieves who commit most household break ins.
Begin by lining the interior
with ½ inch plywood or particle board. It’s easy to
cut or even kick a hole in ordinary drywall. Treat your
“safe” closet’s door as if it were a point of entry
to your home. Use a metal-clad solid door core.
Make sure it’s carefully fitted into a sturdy frame. A
third hinge in the center adds resistance to prying on that side.
Because most closet doors swing outward, you’ll want to secure
them with metal door pins. If the door swings inward, fasten the
door stops to the frame with the longest screws possible.
On the latch side, install a strong deadbolt lock. Protect the door from being pried open by installing a heavy metal strip along the latch edge, as shown.
This
is a great way to protect those valuable family items, and potentially
dangerous items such as guns, if you do not wish to go to the trouble
and expense of a real safe.
