Steps:1. Some screen doors come with excellent instructions. If so, read these carefully before you get started. Decide which side the hinges will mount. In most cases it should be hinged on the same side that the entry door hinges.
2. Start by attaching the entire frame along with the hinges on the side of the door (figure A). To make this easier, some manufacturers provide an index hole to help you get started.
3. Use a self-centering drill bit to make installing hinges easier, as the outside sleeve of the bit retracts allowing the pilot bit to place the hole directly in the center of the hinge hole. After drilling the pilot hole, secure the hinges with the screws provided in the kit.
4. Measure the height of the door to determine the length of the hinge plate. Mark off the length on the hinge plate and use a hacksaw to easily cut away the excess (figure B).
5. Removing the glass from the storm door will make it much easier to handle while securing it in place. Use your foot to support the weight of the door. Lift your heel to guide it into place. Once the door is lined up in the frame, use the screws provided to secure it in place along the outside frame.
6. Open the door and install flat head screws through the hinges and into the door jam. Once again use the self-centering bit to drill pilot holes for this hinge installation. When fastening the screws, it is important not to over tighten them. If you do, it can distort the hinge causing the door to not open and close properly. Tighten until it's a nice, snug fit.
7. The drip cap is a J-shaped strip that is designed to catch the water that comes down the side of the house and channel it away from the doorway. Apply some caulking to the strip before installing it in place over the top of the doorframe as a little insurance to keep any water from running down behind the drip cap.
8. Slide the drip cap in place. It should extend just beyond the left and right sides. Use the screws provided to secure it in place.
