Ask a Question

This is the original and authentic PET TEK Product,

Beware of counterfeit cat flaps which are made of inferior plastic and do not carry the `Catwalk - New Zeland` logo on the flap.

The telltale on these `knock-off` products is a diagram of workman performing the impossible task of cutting through a pane of glass using a multi saw.

The Catwalk® Glass Fitting Maxi Dual Glaze pet door is designed for glass panels from (3mm – 28mm) in thickness, and makes it suitable for single and double glazing applications.

Glass cut-out size

X = 267mm diameter +100mm glass tolerance so overall width of glass must be 367mm.

If you do not have 367mm in the width of your glass this product will not fit. Before purchasing we highly recommend you consult a qualified glazer. 

Please note: the pet door cannot be installed into an existing tempered glass or double glazed window. The glass panel would need to be replaced with the hole already cut at time of manufacture for the pet door to be installed.

We recommend that customers use the flap size above to cut a hole in a cardboard box to see if the cat/dog will fit through it ok.

  • Overall size: 304mm diameter
  • Application: Glass fitting (3mm – 28mm)
  • Pet size: Large cats and small dogs

Ask a Question
  • I’ve already got my French doors so would I but the flap from you and have it fitted in to a new pain of glass

    Yes, that's right - a local glazing firm can quote on the new pane of glass with a hole in it for the cat flap for you. Thanks.

  • Can replacement doors be purchased if they crack or break

    It is covered by a 3 year manufacturer warranty - if the clips or door breaks then they will send out replacements. Thanks.

  • Hi is this the only size cat flap for a glass door that you do. My glazier seems to think it’s very large. I was just wondering if you sell a slightly smaller one. Thanks

    If you just want a 4 way locking cat flap, no microchip, then the Cat Mate 210W is a smaller option for a glass install?

  • When will this product be available to order?

    Hello - they are on a container ship at the moment which is due to reach the UK on 16th April I believe. Shortly after that we will have more stock of them. Thanks.

  • Is the flap/ door wind and sound proof ? Does it flap open by the wind or only when pushed? Is it easy to clean as looks great in the pics when new but expect can get dirty and need cleaning. I currently have a Catmate in a fixed glazed side panel but am replacing the windows so thought I would get a smart new one but want to be sure that the authentic Pet Tek G-SDDC performs as well/even better - can you confirm this. Thank you

    It's not really wind or sound proof, no. It is a thin layer of plastic so you will feel a draught from it. It can be cleaned in situ, or you could unscrew it and take it off to clean more thoroughly. The manufacturer will be able to give more details if you are still concerned. Thanks.

Ideal for sliding doors

The delivery was fast and the item was well packaged. I would recommend this product if you have glass sliding doors as the outside part of the flap only protrudes 11mm. Recommend

New door for a new door

It is with the door manufacturer being fitted - door not being installed until end of January but it looks like it should do the job perfectly.

Transparent catflap

It looks good but has not yet been fitted into a new glass door so I’m unable to review its performance.
