b) In PVC/uPVC/Metal
**Magnetic Cat Flaps will NOT WORK if installed directly into a
surface containing metal. The unit must be isolated from these materials
in a wooden frame (not provided).
Using the horizontal line as a base, draw a square with minimum
dimensions of 306 mm x 306 mm. (This will be the external dimensions of
your wooden frame).
Cut out the square with a jig or keyhole saw. Fit a wooden frame to the
hole with internal dimensions of 169 mm x 169 mm. The enclosed cutting
template can be used to ensure an accurate cut out.
It is within the wooden frame that your cat flap should be fitted to ensure
that is fully isolated from any metal (Fig. 4).
