General DIY Installation ProcessInstalling this pet door is a quick process that requires no specialized hardware or screen removal:Positioning: Choose the corner or baseline location on your screen door where you want to place the pet flap, adjusting for your pet's height.

Snapping the Frame: Align the interior and exterior halves of the plastic frame on opposite sides of your current mesh. Press and snap them tightly together until they lock firmly into place.

Cutting the Mesh: Use a utility knife or sharp razor to carefully cut away the screen material inside the newly snapped frame opening. This detaches the swinging flap area so your pet can pass through.
