Cat Flap/Door Tunnel Extender - For CAT DOOR NOT PET DOOR

Worked as expected. I went through outside R/R siding, and inside 5/8 sheetrock. Did not need instruction, but did read what was there. That info is sufficient. Frame-out wall cavity. The long screws provide will not reach through to secure two sides of unit together. Also, the plastic tunnel is soft. Better to have that rest on a wood base. Framing not a problem if you have normal 2 X 4 studded wall. (Use 2 X 4.) I needed two tunnels to achieve proper outside overhang. This required taking nearly an inch off the second tunnel. Not a problem using 1" X 30" belt sander. Mark your cut with masking tape. Take your time. Don't get burnt.

SureFlap tunnel extender was just what we needed when adding insulation to the wall where the SureFlap pet door was already installed. Our kitty just has 2 more inches of tunnel to travel, and more time to look outside before she leaps. Easy to install, arrived on time and in perfect condition.

The only problem with this was it was sold out and it a little while for me to get it. Once I did, it works great, it made my life so much easier having the dog door! I used some outdoor sealant around the edges just to be overly cautious, but it fit right into the hole and the dogs loving coming and going.

To Extend the Cat Door inside the wall for the my Mini Doxie to get outside!

Our house was built right after WWII and is well insulated with thick walls. With this extender, we could put the cat door thru’ the wall which is where we wanted it !

Easy to add to the main unit!

door works O.K. So does sensor for the two cats at 6 months the control knob keeps on falling out

It works great and if you’re installing it into a wall you’ll need it.

I recently installed the Sureflap Cat door going from my house out to my garage, These tunnel extenders were perfect! They hold up well and connect easily.

Utile si tienes gatera sureflat y necesitas largar el tunnel

Da die SureFlap Katzenklappen finde ich die besten sind, stabil, hochwertig, sehr funktional - ist auch diese Tunnelverlängerung ein Spitzenprodukt. Wenn man diese Verlängerung auf Grund von baulichen Gegebenheiten benötigt, ist der Einbau in Kombi mit der Klappe sehr einfach!

A good value for money microchip cat flap. I have two cats attached and it works perfectly for them. Easy to install in a solid door and quiet when working.

Dovrebbe far parte di un kit insieme alla porticina, perché comunque è fondamentale per creare un passaggio nel muro. Di questi oggetti ne servono diversi, a seconda dello spessore del muro. Da considerare che ognuno copre pochi centimetri (circa 5), quindi per una parete esterna ne possono servire 3,4,5,6 o più. Il prezzo varia molto, con oscillazioni da 7 a 18 euro a pezzo. Quindi teneteli d'occhio un po' se potete e volete risparmiare un po'. La porta, anceh se non riguarda direttamente questo oggetto, è veramente fantastica.
