PetSafe Staywell, Deluxe Tunnel Extension, Woodgrain, 47.75 mm, Easy Fitting

I discovered that I didn't need this so I've not used it.

We needed 4 of these to extend our cat flap, worked great.

They are OK but they do not fit together well so be prepared to have glue on had to keep them together.

Matching extension to door flap, excellent for extra wide/super thick doors and walls, so check what you want need on company website which is very helpful. My door was marginal so ordered this in case of need, but in the end main kit perfect size so returned this, no quibble. Super service

Used 6 in total for a tunnel through cavity wall.

Fits nicely together and is quite easy to install. The screws are a pit close to the edge of the opening when installing in to masonry but otherwise very good.

Make sure you have the right glue

Terrible and misleading product. Only one extension piece per box (photo shows two) and it has taken five to go through the cavity wall so proves over priced. It is flimsy and not up to coping with frequent use.Just really disappointing product.
