With the 9 cm metal extension, all Hauck safety gates can be quickly converted into a stair gate. The extension is simply attached to the safety gate using the practical connector piece. In addition to the 9 cm extension, the Hauck safety gate can also be expanded with a 21 cm extension. Thanks to the variably usable extensions, both narrow and wide openings or staircases (up to 123 cm) can be made childproof. If you have a stair railing with round bars, you can additionally secure the child safety gate with the separately available Y-spindles along with the 9 cm and 21 cm extensions.

This results in the following options:
with extension: 9 cm = opening widths of 83 - 90.5 cm
with extension: 9 cm + 9 cm = opening widths of 92 - 99.5 cm
with extension: 21 cm = opening widths of 95 - 102.5 cm
with extensions: 21 cm + 21 cm = opening widths of 116 - 123.5 cm
with extensions: 9 cm + 21 cm = opening widths of 104 - 111.5 cm.
