Staywell PetSafe, 700 Series Tunnel Extension, 5.8 mm, Easy, Precise Install

So easy to install, good quality. Sizes on the spec were spot on so fitted like a glove. Tidy appearance. Would definitely recommend as looks so much tidier than a brick or would surround. Easy to wipe and keep clean when pet comes in wet.

Only flap available in brown, so needed these to go through 9" wood wall .Flimsy at this length at 1st but now stabilised with a wooden tunnel and insulation boards.

1. Measure the thickness of the door you wish to place the catflap into.2. Cut tunnel pieces along the grooves with kitchen scissors to the thickness of the door (Carefully).3. Assemble the tunnel frame (lining it up with the lugs on the tunnel and holes on frame) and attach it to the outer part of the catflap (you can use glue but it's not essential). 4. Mark in pencil the outside shape of the tunnel frame on the outside of the door ( make sure that the outer frame is high enough to clear the frame on the door).5. Cut a hole in the door and slide tunnel into the hole. Mark holes for screws (on the outside of the door) and drill the hole marks.6. Place inner part of the catflap, (so slit for flap locking barrier is at the top) on the inner side of the door. Slide bolts into holes until they protrude through the outer catflap holes (depending on the thickness of door you may need to buy longer bolts) and place nuts onto bolts (nuts go on the outer frame between the raised lines).7. Do the nut and bolt finger tight and line up the inner frame so that it's lip sits within the tunnel sides then tighten screws and line nut up with the two raised lines either side of the nut on the outer frame ( this will stop nut turning when tightening screw).8. If necessary, cut the screw thread so the outer flap can close ( WARNING if you use a Dremel type cutting wheel the grinding will make the screw and nut hot enough to melt the plastic so do a little off of each screw at a time). 9. Stand back and admire your work ( push flap in and out to make sure of free movement) and you're done.

Yup I got it all assembled with the cat flap and screwed into the door and then realised that the tunnel had an up and a down. So, take it all apart., re-drill the holes for the screws, put it all back together again. It was lucky that I didn't glue it as recommended, otherwise it would have gone in the bin.

The cat flap has a template you cut the hole that big, this is then supposed to fit in the hole, it’s too big. If you cut the hole bigger the screws will have nothing to screw into.Waste of money and now I have a hole in my door that is going to get wet on the internals of my door.Had to keep cat flap locked…. Very disapppinted!

Works great with out cat flap, especially if u have a wide door

Far cheaper than buying direct from the supplier. A little tricky to fit and a little flimsy but we have it on an internal door so absolutely fine and fit for purpose. I wouldn’t use for an external door

No idea why this is recommended with certain flaps. This is too large so you have to remove either the top or bottom piece leaving 3/4 to block any hollow door.The only reason it's not the lowest score is that it still can work with modifications and it's better than just leaving a hollow door between the flaps.

Wer gedacht hat, den Einbau in 5 Minuten hinter sich bringen zu können, der sollte sich mehr Zeit nehmen. Mein Mann ist handwerklich begabt, aber es wäre leichter gewesen, einfach die Tür dauerhaft offen stehen zu lassen. Aber wer geduldig bleibt, dem wird die Katzenklappe mit diesem Zusatzstück Freude bereiten.

Perfecto

Installed in an interior door, it looks very neat, you can cut it very nicely and click it together.

Facile a monter et extensible et recoupable
