Ideal for a large cat or small dog, the Pet Tek Glass Fitting Cat Door in clear has a professional design and will endure year after year of daily use.

The Catwalk Clear 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.

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.

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. 

  • Flap size: 195mm x 185mm
  • Overall size: 304mm diameter
  • Application: Glass fitting (3mm – 28mm)
  • Pet size: Large cats and small dogs
  • For sliding doors: The G-SDDC protrudes 17mm on the inside and 11mm on the outside of the door its connected to. Please ensure enough clearance for sliding doors to pass the pet door.

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.

Clear cat flap - transparent authentic Pet Tek GSDDC maxi dual glaze clear pet door - cat out of glass, £26.99 and 2. Clear transparent cat flap- authentic Pet Tek GSDDC maxi dual glaze clear pet door £16.89. Thank you. Julia.

    Sorry, I am not sure why that is, I will check with our web developer. They are the same product - I think the cheaper one is without postage and you can choose which postage option you'd like at the checkout - Hermes, or ParcelForce. Thanks.
