We have 2 types of replacement flaps due to our products being improved over the years. This guide will show you which flap you will need for your pet door.
Step 1. Determine the size of your pet door. If you don't know it, refer to our size chart here to work out the size you have.
Step 2. Check either side of the flap on the aluminum frame for the mohair seals.
If it has Mohair seals down each side then you need Replacement flap V3.0
If it doesn't have the seals down each side then you need Replacement Flap V1.9
