I tried to install a security door and ran into a problem.
This is a heavy door, and the screws that support are about 1/4" by 3 "
The screws go into the existing door jam at a right angle, not parallel, to
the "face" of the house.
When I tried to put them in, all I encountered was open space behind the
trim - not wood.
I'm wondering what kind of door frame set-up this might be and what I can do
about it. The house is 2.5 years old.
