1. Most sliding screen doors are mounted on rollers. Tension screws are usually located near these rollers. They can be loosened to allow easy removal of your screen door. Some brands such as Pella doors have the screen doors attached to
rollers suspended from the top of the screen door channel. There are
screws along the interior top edge of the screen door and once these
are loosened, the door will drop enough to lift out of the channel in
the floor.
Remove the host screen door from the sliding channel and lay on flat work surface.

2. Position the pet door on your screen door, spline grooves up. The pet door must be mounted in the bottom corner
For example, most patio screen doors have the screen spline groove to the exterior; the Pet screen door spline groove should therefore be to the exterior as well.

3. Mark the horizontal screen cut location on the sliding screen door frame with a pencil. It is best to mark the cut location an 1/8" in from the end of the H
channel (Overlay flange) attached to the Pet screen door to allow enough screen material
to roll into Pet Screen Door Spline groove. (Point A)
4. Make the same mark at the bottom corner of the overlay flange - bottom corner of your screen pet door; 1/8" in from the end of the H
channel. ( Point B)
5. Using a marker, draw a straight line on the screen from point A inward and Point B upward. Where they intersect is Point C.
