The SureFlap Tunnel Extender fits the Sureflap Microchip Cat Flap and Dual Scan models. It is used to allow SureFlap installation in walls. Each extender adds 2" to the original self-framing depth of the Cat Flap or Dual Scan.

Enough tunnel extensions should be purchased to reach the thickness of the wall but no more. The Micro-Chip Cat Door and the DualScan and Cat Door are both "self-framing" to 2-3/4" and will provide the additional depth. In addition, it will slide shut on the tunnel sections to provide a snug seal.

    These were perfect for installing the SureFlap I bought already through my wall. The pieces just clicked together, and the thickness of my wall worked out so I didn't even have to cut any of the tunnel. Easy solution!

Fit SureFlap MicroChip Cat Flap

1. Make a line on the wall for the cut out that is 6-11/16” wide by 6-11/16” high.

Tip: In order for your pet to be able to fit through comfortably generally the bottom of the cut out should be no more than 3” - 4” from the floor.

2. Double check that there is no electrical, framing, pipes, etc. in the location you are installing the door before cutting.

3. Using the appropriate tools for the job (this depends on the material you are cutting through and if you are unsure then consult a licensed contractor).

Tip: The manufacturer states that you can make a very slight gradual slope towards the outside to insure when installed any water gathering in the tunnel with drain out.

4. Take the tunnel extenders and apply super glue to the corner tabs, then fit them all together. Once the glue dries use weatherproof tape around the outside of the tunnels.

Tip: Do Not glue the tunnels to the pet door.

5. Take one side of the mounting adapter and drill the 4 holes in it using a .15” drill bit. The holes are going to be what holds the flaps to the inside of the house. You can put the screws on the two sides and the top and bottom.

6. Now you can get the cat flap and using the washer screw and shortest screws provided with the door mount the pet door to the adapter.

7. Fit the cat door and adapter through the cut out.

8. Take a pen and mark the four holes you made through the adapter. You should also remove a little material from the wall in order to recess the screw and washer to make it flush to the wall. Remove the door and adapter.

9. Now drill the holes in your wall with the appropriate drill bit for the screw you chose and material of your wall.

10. Now tape the tunnels to your cat door using the same weatherproof tape as in step 4.

11. Mount the cat door with the tunnels and adapter in the wall from the inside and screw it into place through the holes in the adapter.

12. You will see the tunnel sticking out of the wall from the outside, so take the outside frame and second adapter and fit it over the tunnels and against the external wall.

13. Make a mark for the screw holes, then remove the frame and adapter and drill the holes out.

14. Now fit the outside mounting adapter over the tunnel, then the outside frame over the tunnel against the adapter and screw them to the wall.

15. Use some small screws to drill through the top of the tunnel sections and into the frame to secure it.

16. Use a silicone sealant to seal anything that has the potential to get water in it that would leak into the wall.
