Instructions for Replacing
Remove the 4 screws that secure the frame of the pet door.. The pet opening then will pull apart into two pieces.. Use a needle nose pliers to pull the rod out from the old flap, this detaches it from the frame. Insert the rod back into your new flap and into the frame on the other side so it is secured. Re-assemble the two frame pieces back together and replace the 4 screws that secure the frame.
