What to Compare Before Buying

  • Opening size: Compare the stated outer size and flap size with the window, door or sliding door opening you plan to use.
  • Panel thickness: The stated 2 cm panel thickness matters if you are fitting it into a thin surface.
  • Lock mode: Choose the 4-way setting that matches whether you want free access, one-way access or full locking.
  • Pet size: The flap is described for cats and small dogs, so check the pet’s size against the opening.
  • Included fixing method: Confirm whether you want screws, caps and double-sided tape for your installation plan.

What Else You May Need

For fitting, you will need an opening that matches the stated size and thickness. If you are installing it in glass or another finished surface, check that the chosen location is suitable for cutting or fitting before you start.

Before You Decide

Check the outer size, flap size and 2 cm panel thickness against your chosen opening before ordering. Confirm that the 4 lock modes match the way you want to control pet access, and make sure the included fixing method suits your installation plan.
