13. On the outside of your house you will now have the tunnel sticking out of the wall – take
the external frame and other mounting adaptor and place these over the end of the
tunnel.
14. Mark the position of the two screw holes required to mount the external frame and then
drill appropriate holes in the wall.
15. Screw the external frame and mounting adaptor to your external wall.
16. To hold the end of the tunnel in position we recommend using small screws to secure
the tunnel to the external frame as shown in Figure 27.
17. We recommend putting some waterproof sealant between the tunnel and the external
frame to prevent water getting into the wall cavity.
