A Door In A Door. That Is The Whole Idea. Once a dog has learned that the garden is on the other side of the back door, the household runs on a schedule set by the dog. Cutting a framed opening into that door returns the decision to the animal and the doorbell back to the humans. This is the version with an aluminium frame, a magnetic flap and a lock, so the opening can also be closed off when it should be.
The frame is aluminium alloy rather than moulded plastic, which is what keeps the opening square through years of a large dog pushing through it. The flap is frosted PVC with a magnetic strip running down the edge, so it swings easily and then seats itself shut, blocking draughts, rain and noise. Around the frame sits a bristle brush strip that wipes the worst of the mud off a coat on the way through and keeps wind and dust on the outside where they belong.
Three sizes cover most dogs: small, medium and large. The flap aperture is 8.25 by 12.25 inches with a frame of 11.30 by 16.02 inches, and the unit fits doors from 1.06 to 2 inches thick, which is the normal range for solid timber and composite doors. A rotating hinge lets the flap open through a wide arc rather than a narrow slot, and the locking plate stops anything else from coming in the other way. The fixing kit includes stainless screws, hollow T-nuts and decorative caps.
Freedom for them, quiet for you.

Where It Belongs
The obvious installation is a back door that a dog currently scratches at three times a day, whether that is a family home with a garden or a farmhouse with more land than doors. It also suits a utility room or mudroom where the bristle strip does its best work on wet paws before they reach a carpet, and a workshop where a dog comes and goes while someone is working. Because the flap locks, it fits a home where the opening has to be closed at night or when the household is out. Renters who cannot replace the door should check the thickness against the 1.06 to 2 inch range before ordering, since a hollow-core interior door sits at the bottom of that span.

Frequently Asked Questions
Q: What size do I need for my dog?
Size the opening against the flap aperture of 8.25 by 12.25 inches and against the animal's shoulder height, not its length. The general rule is a flap about two thirds of the dog's inside leg measurement. Small covers cats and small terriers, medium most spaniel and collie sized dogs, large retrievers and shepherds.
Q: Will it fit my door?
It fits door thicknesses from 1.06 to 2 inches, or 27 to 50.8 mm, and the frame needs a rectangular cut-out of 11.30 by 16.02 inches. Measure the door panel thickness at the point you intend to cut and confirm it falls in that range.
Q: Does the flap keep the weather out?
The flap carries a magnetic strip that seats it shut, and a bristle brush strip runs around the frame. Together they stop the worst of draughts, rain and dust, which is what makes a pet door usable through a northern winter.
Q: Can I lock it?
Yes. The unit includes a locking plate and metal plate design, so the opening can be shut off completely at night or while you are away.
Q: Will my dog learn to use it?
Almost all of them do. Prop the flap open for the first day or two so the animal gets used to passing through, then let it swing shut. The magnetic strip is light enough for a small dog to push through.
Q: Is it safe on a glass door?
This unit is designed for timber and composite door panels where a rectangular cut-out can be cut. A glazed panel needs a different solution, so message us and we will advise before you order.
Q: What is in the fixing kit?
Stainless steel screws in two lengths, hollow T-nuts, decorative caps and an exploded installation diagram. A basic drill, a jigsaw and a screwdriver are the tools most installers use.
