An adaptor is a long skinny panel that gets installed next to pet door insert.

Adaptor is used for 2 options:

  1. close BOTH glass and fly screen door into an adaptor, and/or
  2. If your female latch is sitting inside the channel, you will always require an adaptor as you will need to relocate internal female latch to an adaptor.

Adaptor comes in 3 sizes: 2.1m, 2.5m and 3m tall

You will need to cut the adaptor and fit it into your track.

Wonderful feature about adaptor is that you can lock your security screen door into adaptor, enjoy breeze coming inside your home and keep unwanted bugs outside!
