I am selling used aluminum window guards for $12 each.
I have seven guards.
They are all the same size.
The height of the vertical (up-down) bars is 19 1/2".
The width of these guards is adjustable, from 27 7/8" maximum, to 16" minimum.
These guards have no deformities, but have some areas where the paint has been scratched off.
They have been cleaned and are in very good condition.
Remember two considerations to decide the correct size window guard to fit your window:
1) The height of the guard will determine how much you can lower the top window (because the top window will hit the guard).
2) The width of the guard has to fit the width of your window.
There are three holes for screws on each vertical bar.
The screw holes are 3/16” in diameter.
I do not have screws.
