You can transform our Hauck door gates and stair gates in no time at all thanks to this metal extension. Just slip the extension on the safety gate - No problem thanks to the practical connection piece. Our extensions are compatible to our Trigger Lock Safety Gates, the Squeeze Handle Safety Gate and the Deluxe Wood and Metal Safety Gate. Depending on the safety gate, different extensions can be combined. For example, you can combine two extensions of 7 cm, an extension of 7 cm and one of 14 cm, or even use the two extensions of 14 cm.
