What to Compare Before Buying
- Installation space: The flap body measures 22 cm x 20 cm x 3 cm, so compare that with the space available in your door, window or wall.
- Pet opening size: The opening is 15 cm x 15 cm, so check that it suits the pet you want to use it.
- Lock setting: The 4-way lock gives four entry and exit options, so choose the mode that matches how you want the flap controlled.
- Fitting method: Screw fittings and a cutting template are included, so make sure you are happy to follow a cut-out installation.
Compatibility, Size and Fit
This flap is stated for interior and exterior doors, window and wall fitting, including wall tiles, uPVC, glass doors and wooden doors. The exact suitability depends on the opening size, the material being cut and the space available around the fitted frame.
Because the flap opening is 15 cm x 15 cm, the pet itself needs to be a suitable size for that opening. The product is described as suitable for small pets, including kittens and puppies.
Before You Decide
Check the overall size, flap opening and fitting location before choosing an offer. Confirm that the 4-way lock setting matches how you want to manage access, and make sure the included fittings and cutting template suit your planned installation.
If you are fitting it into glass, uPVC, a wall or another fixed surface, compare the opening size carefully before starting the cut-out.
Planning the Pet Door Setup
A simple first step is to decide where the flap will sit before cutting anything. Measure the intended position, check the space around the frame and confirm which of the four lock modes you want to use most often. That makes it easier to plan the installation before the opening is made.
