The absolute best way to measure for new window screens is to measure the old screens. Measurements are taken to the outside edge of the aluminum frames. Measure near the corners as sometimes screens are bowed in near the middle of the frame.

Common hardware for these Half Screens are:

• Leaf Springs on top or side
• Tension Springs on top or side
• Bale Springs on top
• Lift Tabs to help in removal of screen
