PetSafe Extreme Weather Large Aluminium Dog Door – PPA19-16905

The PetSafe Extreme Weather Large Aluminium Dog Door (PPA19-16905) combines a tough aluminium frame with a triple-flap insulated design to provide a durable pet door for larger, active dogs.

Designed for exterior doors, kennels, workshops and other suitable installations, the three-flap system helps reduce draughts and cold air passing through the pet door while still allowing your dog easy access.

Important: This particular model is designed for doors approximately 37.5mm to 50mm thick. If you are installing into a thinner uPVC door panel, please see our alternative Large Dog Flap for uPVC Doors.

Heavy-Duty Aluminium Frame for Active Dogs

The aluminium frame is designed to provide greater strength and durability than a conventional lightweight plastic pet door. This makes it particularly suitable for larger or more active dogs where a robust frame is important.

It is also an excellent option for installations in kennels and exterior buildings where the dog door may receive frequent everyday use.

Triple-Flap Extreme Weather Design

Instead of relying on a single flexible flap, the PetSafe Extreme Weather Dog Door uses a three-flap system.

The outer flexible flaps create the main opening while an additional insulated centre section provides another barrier between the inside and outside.

This design helps:

• Reduce cold draughts through the pet door
• Reduce air movement through the opening
• Improve insulation compared with a conventional single-flap pet door
• Provide additional protection during poor weather

Insulated Centre Flap

The lightweight centre section provides an additional insulating barrier between the two flexible outer flaps.

Although relatively slim, when the three flaps are correctly positioned together they create multiple barriers against outside air rather than leaving only a single flap between your home and the outdoors.

Adjustable Flap Alignment

The triple-flap arrangement can be adjusted during installation so that the flaps align correctly after the dog door has been fitted.

Correct alignment is particularly important with a multi-flap pet door because it allows the magnetic closures and insulating sections to work together effectively.

Flexible Flaps with Magnetic Closure

The flexible outer flaps are designed to move easily when your dog passes through and then return towards the closed position.

Magnets help hold the flaps in position when the pet door isn't being used, helping reduce unwanted movement caused by normal draughts and wind.

Slide-In Closing Panel

The PetSafe Extreme Weather Dog Door includes an internal slide-in closing panel that can be used when you don't want your dog to use the door.

This provides a simple way to close the pet door overnight or whenever unrestricted access isn't required.

Suitable for Large Dogs

With a generous 260mm × 413mm flap opening, this Large model is designed to provide comfortable access for many larger dogs.

When choosing a pet door, we recommend measuring your individual dog rather than selecting a size purely by breed. Measure your dog's widest point and compare it with the usable flap opening before ordering.

Important Clearance for the Closing Panel

The internal closing panel slides vertically into position, so sufficient clearance needs to be available around the pet door to insert and remove it.

Please check the dimensions and available space on your door carefully before cutting the opening.

Important – Check Your Door Thickness

This version is designed for doors approximately 37.5mm to 50mm thick.

This is particularly important if you are considering installation into a uPVC door. Many uPVC door panels are considerably thinner than this.

For a suitable thinner-panel option, see our Large Dog Flap for uPVC Doors.

Security Information

A large dog door creates an opening that may be big enough for a person or small child to pass through. A pet door should therefore never be considered a security device.

Consider the location of the dog door carefully and make sure appropriate security measures are used elsewhere in the property.

Young children should also be supervised around large pet doors.

Frequently Asked Questions

Is the frame plastic or aluminium?

This model has a robust aluminium frame, making it particularly suitable for larger and more active dogs.

How many flaps does it have?

The Extreme Weather design uses a three-flap system, including an insulated centre section designed to help reduce heat transfer and draughts through the opening.

What thickness door does it fit?

This model is intended for doors approximately 37.5mm to 50mm thick.

Can I fit it into a uPVC door panel?

The thickness of the panel needs to be checked carefully. Many uPVC door panels are thinner than the minimum thickness required by this model. We offer a Large Dog Flap suitable for uPVC door applications.

Can I stop my dog using the door?

Yes. An internal slide-in closing panel is supplied so the opening can be closed when required.

Can I replace the flap if my dog damages it?

Yes. Replacement flap PAC11-11039 is available separately, helping extend the working life of the complete dog door.

How do I know whether the Large size will fit my dog?

Measure your dog at its widest point and compare those measurements with the 260mm wide × 413mm high flap opening. Measuring your individual pet is more reliable than choosing solely by breed.

I'm unsure whether this will fit my door. Can you help?

Yes. If you're unsure about your door construction or thickness, send CatFlaps.co.uk a photograph of the door together with its approximate thickness and your dog's measurements. We'll be happy to help you choose the most suitable pet door before you start cutting.
