Staywell pet flap and tunnel extension (The Hockering GU22)

Had this for a while but never used. Two items for a pet flap in a door - in our case for cats. The Staywell Pet Door, small model (236x198mm) and a tunnel extension if the door /brick is thick and needs a bit of plastic to make a smooth tunnel. The pet door packet never opened and includes instructions. If you reply, please say when you could collect this from Pyrford, Woking.
