Permanent Solution | Tools Required: Screwdriver/ Hack saw
This option is popular for people wanting full functionality. It is an aluminum 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 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 per 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.
