The Chicago pressure gate can be fitted straight from the box, with a standard fit of 73-80cm. However, it's no problem if your space is bigger than this as 2 extensions are included so it can fit openings of 73-93cm. A real bonus is that the pressure indicators will show you when the gate has been installed correctly, giving you peace of mind. And the gate won't cause any inconvenience to adults or older children as it can be opened in either direction, while featuring a triple locking handle to keep youngsters safe.
