Question about PetSafe Petporte Smart Flap

I have not bought anything extra. Ps. I rebuilt the disc and replaced it with the replica. This way I can put everything back without any problems.

I put the door in wood, so I can't answer the question.

The item is delivered ready to use in a box. Will not be customised.

This is a plastic booklet and is included in the delivery!

what is a glass adapter?
