Product Overview
A four-way locking pet door for owners who are tired of being the doorman. It fits into a door panel, lets a cat or a small-to-medium dog come and go on their own, and gives you four lock settings so you decide when that is allowed. What sets it apart from most flaps at this price is that the maker actually publishes its measurements — a 21 cm door opening in a 26 × 8.5 × 31 cm frame — and ships a cut-out positioning template in the box, so you are not guessing with a jigsaw. Moulded in ABS and PC, with nothing to charge and nothing to break.

Important Information
-
Do not cut anything until the door and template arrive. The manufacturer is emphatic about this, and states that it will not provide returns or repairs where the hole was cut without the official template. Wait for the box.
-
Which 21 cm is it? The maker gives a single "door opening size 21cm" figure without saying whether that is the width, the height, or both. We would measure your pet against 21 cm in whichever direction is tightest for them, and ask us if you want us to chase the supplier for a full opening spec.
-
Two of the four modes are printed identically. The manufacturer's own list reads "1. No in or out, 2. Can go in or out, 3. Only in and out, 4. Only in and out" — items three and four are word-for-word the same in the original. In practice a four-way flap is normally closed / open / in-only / out-only, but since the supplier has not actually said which is which, we are not going to assert it. If a specific directional lock is why you are buying, message us first.
-
Maximum door thickness is not published. The 8.5 cm frame depth suggests it suits a substantial panel, but the maker gives no minimum or maximum. Measure your door and ask us if it is unusual.
-
The supplier's title mentions glass doors; its installation notes describe cutting a panel with a template. We are selling this as a flap for a door panel you can cut. Do not attempt to fit it to glass without a glazier.
-
Fitting is irreversible. Once the panel is cut, it is cut. If you are not confident, have it fitted.
- Introduce your pet gradually: prop the flap open, encourage them through with treats, then let it swing.
- If it opens to the outdoors, keep microchip details current and consider locking it overnight.
- Wipe clean with a damp cloth. No solvents on the plastic.
Frequently Asked Questions
Will my cat fit?
Measure the widest part of your cat's body and their shoulder height, and compare both against 21 cm. Most cats clear that comfortably; a very large cat or a broad small dog may not.
Does it really come with a template?
Yes — the manufacturer says the positioning template ships with the product, and warns against cutting before it arrives.
Is it microchip or sensor operated?
No. It is a mechanical flap with four manual lock settings. Any animal that can push it and fits through it can use it.
Can I set it so the cat can come in but not go out?
The manufacturer lists four modes and describes two of them identically, so we cannot confirm which directional lock is which. Ask us before ordering if that setting is the reason you want it.
Can I fit it to a glass or metal door?
Not without a specialist. The instructions describe cutting a panel to a template, which in practice means wood or uPVC.
Are screws included?
None are listed. Plan on your own fixings.
How thick a door will it fit?
Unpublished. The frame is 8.5 cm deep, but the maker states no thickness range — measure yours and ask us if in doubt.
