- For Trigger Lock and Squeeze Handle Safety Gate - Easy handling - Easy assembly - no drilling necessary - Different combination possibilities with prolongations of 7 and 14 cm You can transform our hauck and Disney door gate into a stair gate in no time at all thanks to this metal extension. Just slip the extension on the safety gate - without any problems thanks to the practical connection piece. Our extensions are compatible to the 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 two extensions of 14 cm. From this result the following options: with extension: 7 cm = opening widths from 82 - 88 cm with extension: 2 x 7 cm or 1 x 14 cm = opening widths from 89 - 95 cm with extensions: 1 x 7 cm + 1 x 14 cm = opening widths from 96 - 102 cm with extensions: 2 x 14 cm = opening widths from 103 - 109 cm
