This is the standard-width version, covering openings from 74 to 80cm, which takes in most internal doorways in a British house without needing an extension panel. If your gap is wider than 80cm, take the 74–87cm model instead — the mechanism is identical, only the range differs.

What you are paying for is the door behaving properly. It closes itself from anywhere between 30 and 90 degrees, so it latches whether or not the last person through remembered. The handle slides and lifts with one hand, which is the difference between a gate you use and one you leave propped open with a shoe. Two rotating locks at the base decide whether it swings both ways or one only, and there is a double locking mechanism on the latch itself.

• Fits openings between 74cm and 80cm
• 78cm tall with 5cm bar spacing
• Self-closing door, 46cm wide
• Double locking mechanism, slide-and-lift handle
• Selectable one-way or two-way swing
• Lead-free metal frame, 4.5kg; tapes and screws included

Measure the narrowest point. Door frames are rarely square, and the number that counts is the tightest part of the opening, not the widest — a gate fitted to the wide measurement will sit loose at the other end. Take the measurement at the height the gate will actually sit.

Who it's for: Standard doorways, kitchens and hallways where a dog needs to be kept to one side of the house, and anyone with their hands permanently full.
