Transparent flap size
Pet Porte Smart Flap has a 16cm x 16cm door making it a great size
for most cats of up to 7kg in weight to easily get through. This
includes big domestic cats including the Norwegian Forest Cat and
The outer plastic case of the cat flap measures 23cm wide by 23cm high and is approx 4.3cm deep. It comes in two parts that bolt together – an inside part with the controls and the flap itself, and an outside part with a porch that houses the scanner. These are connected together by a wire.
Dimensions of the external sensor porch
The porch that contains the scanner coil which reads your cat’s microchip is 19.5cm wide by 14.2cm long and 3.7cm deep. That’s about the same size of a CD case. The reason it protrudes is so that it is positioned over your cat’s microchip when your cat wants to open the door.
What size hole to cut
The size of the hole you need to make for fitting can be either a 212mm diameter circular hole or a rectangular hole of between 163mm by 163mm. It will also fit existing cat flap holes below 220mm x 220mm. The cat flap clamps together by use of the two bolts (supplied).
Minimum and maximum thicknesses of installation
The minimum thickness for your door or window is only a few millimeters so the cat flap can be fitted in a single pane of glass right up to a 4cm thick door.
If you are installing the Pet Porte Smart Flap in a wall, the maximum width of your wall can be approx 38cm or 15 inches. This is due to the length of the wire that goes from the inside part with the buttons on it to the outside part that houses the microchip scanning coil.
How many wall tunnel pieces to order
Wall tunnel pieces are each 4cm deep, and you get one 4cm piece included as standard. The wall tunnel segments are optional but do give a very neat professional look to the installation so are recommended.
Calculate the number of wall tunnels by the depth of your wall in centimeters, minus 4 centimeters for the wall tunnel that is included, divided by four centimeters. If you have a remainder (eg. 6.4) you would need to order one extra segment which you can cut down.
