For walls and thick doors
The flap’s own tunnel is 70 mm, which suits most doors. A brick or block wall, a thick timber door or a double-glazed unit with the adaptor needs more. Each extender clips onto the last and adds 50 mm; measure the wall, divide by 50, round up.
Lining the hole
In a wall the extenders also line the cut-out, so your cat walks through a smooth white tunnel instead of raw block.

Before you buy
How many do I need?

Does it fit the Microchip Pet Door?

Can I cut one down?
Yes, the last extender can be trimmed with a fine saw to finish flush with the wall.
