My sister has she would like to lock partially open - a typical glass
sliding patio door - except it appears to have been installed
backwards! The sliding porting of the door is on the inside of the
house. The fixed portion is outside. She would like to be able to
'lock' it open a couple of inches for air flow. If the sliding portion
was outside, a simple locking bar against it and the fixed portion
would work, but as it is reversed, the bar would be on the outside. I
thought about putting a locking pin in the top or bottom, but there is
not enough clearance to drill the frame with out hitting the glass. I
suggested a door lock chain, but she doesn't like that idea.

If I was her big brother, I'm sure I could figure it out, but alas, I'm
her younger brother...


My sister also has one of those, but I don't
remember how it looks. Looking at my door as if
it were put in backwards, you could drill through
the top part of the frame and into the door. On
my door you would drill through a 1-1/2" thick
piece before getting to the door. The glass in a
door doesn't usually extend more than 1/2" above
the bottom of the top part of the frame. Your
door could be different but I would have another
look at drilling a hole(s)to slip a nail into.
Good Luck.
