The easiest way to tell if you have a V1 or V2 pet door is if your pet door and flap has adjustment screws at the top of the flap, this is the V2 model.

You can find flap adjustment and replacement instructions at the end of the installation videos below, or follow these easy steps:

3. Using a flat head screwdriver, pry open the metal strip/bar that clasps the flap in place
4. Position new flap in frame, push down the strip/bar to clasp the flap in place and secure with screws
5. Screw the pet door frame back in place

V2 Flap Replacement/Adjustment

1. Remove screws on flap holder
2. Remove flap
3. Replace flap and align
