Oh, they also had a fixed plate or other anti-theft device that has to

Actually, not that I think about it for a while, there weren't rollers
on the top but a slot that straddled the upper guide. *It was the little
flat plate that went on that was the anti-break-in device that would
keep the door from being lifted out of the track when in place...

Fortunately, I've not had a set of the stinkin', drafty, leaky things in
long enough now I'd kinda' forgotten...

One of the advantages of Crestline doors, if they're still built the
way mine was, is that no anti-theft device is required.

Instead of leaving room above the slider so the panel be lifted out,
there's an interior trim piece along the top of frame holding the door
in. If you remove the screws holding the trim in place, the slider
falls into the room.

There's virtually no gap between the top of the slider and the frame -
just enough for a little furry weather strippping, similiar to what
you find on vinyl replacement windows. Security and weatherproofing in
one smooth move. In addition, my door is all wood, so the trim piece
adds a nice feature. Form and function.
