This option is popular for people wanting full functionality. It is an aluminium extrusion that fixes to the side of the Patio Pet Door. It creates a channel for both the sliding door and the screen door. Simply move your latches from the door frame onto this adapter and you can then lock both doors together as you usually would. Without this, you can only lock one door at a time onto the pet door.

This is also the most secure solution as both doors are locked. We recommend you use the adapter in conjunction with the Security Pack for the best security. 

The adapter is 10cm wide and will not work with stacker doors.

The adapter comes in 2 pieces which are lengths of 105.5cm making it viable for shipping. This gives you a total height of 211cm If your door is taller than this you will need extension pieces and an adapter add on piece. See here. The adapter can also be cut down for doors shorter than 211cm.
