Product Overview
If your dog waits by the back door and you keep getting up to open it, an insulated dog door fitted into the door panel gives both of you the afternoon back. This is a rigid plastic pet door built for real doors — interior or exterior — with a backplate that seals against the frame and a flap the manufacturer rates for temperatures from −40 °C to extreme heat. Unlike a fabric or magnetic screen flap, it fits into a cut-out and stays put. It comes in two sizes with published dimensions and, unusually for this kind of product, a cut-out template and step-by-step instructions are included in the box.

Important Information
-
The two figures above are the sizes the manufacturer publishes, and it does not say whether they describe the outer frame or the flap opening. On a product like this they are almost certainly the overall frame, which means the usable opening your dog passes through is smaller. We are not going to invent a second set of numbers. If the exact opening decides whether this fits your dog, contact us before ordering and we will chase the manufacturer for it.
-
The manufacturer describes this door as lockable with a privacy cover, but the specification sheet does not explain the locking mechanism. We are repeating the claim as theirs rather than describing a mechanism we cannot confirm. If a secure lock is the reason you are buying, ask us first.
-
Installation is not reversible. This door fits into a hole cut through the door panel. Measure twice, and consider having it fitted if you are not confident with a jigsaw or hole saw.
-
Measure your dog, not just the door. The standard method is to measure the width across the widest part of the body and the height from the floor to the top of the shoulders, then choose an opening comfortably larger than both. Between sizes, size up.
- Maximum door thickness is not stated by the manufacturer. If your door is unusually thick — a solid exterior door with heavy insulation, for example — check with us before ordering.
- Screws and fixings are not listed in the package contents. Assume you will need your own.
- Insulation and weather sealing are described by the manufacturer but no R-value, air-leakage figure or weatherproofing rating is published, and none should be assumed.
- A pet door is an opening in your home. If it leads outdoors, keep your dog's microchip details current and consider closing the door at night.
- Wipe the flap and frame with a damp cloth. Do not use solvents on the plastic.
Frequently Asked Questions
What size opening will my dog actually get?
The manufacturer publishes 43 × 35.5 × 4 cm for the Large and 35 × 29 × 4 cm for the Small, without saying whether that is the frame or the opening. Treat it as the frame and expect a smaller usable opening. Ask us before ordering if the difference matters.
Will it work on an exterior door?
Yes — that is what the sealing backplate and cold-rated flap are for. The manufacturer states the material handles −40 °C and extreme heat.
Do I need to cut a hole in my door?
Yes. This is a panel-mounted pet door, not a magnetic screen flap or a tension-fitted gate. A cut-out template and instructions are included to help you mark it accurately.
Can I lock it?
The manufacturer describes it as lockable with a privacy cover but does not detail the mechanism, so we cannot describe how it works. Ask us before ordering if that is your deciding feature.
Is it microchip operated?
No. It is a purely mechanical flap with no sensor, reader or battery. Any animal that can push the flap can use it.
What is the difference between the paw-print and square patterns?
Nothing functional — it is the decorative pattern on the flap cover. The Small size ships with the paw-print cover and the Large with the square cover. You cannot mix them.
