Review: Perfect fit for Aldi bought Hauck open n stop gate. - Great extension to go with hauck open n stop gate I bought from aldi,(for same price as extension by the way) fits great, I was worried as my stairs are different widths at top from bottom so I had to remove the internal screw and end for it to fit but once pressure screwed in place it's completely solid. Great for keeping boisterous puppy downstairs. I saw another review that said it didn't fit with the aldi gate but it fit mine perfect. Very happy with purchase, only negative I can give is ridiculous packaging it came in, as shown in pic, could have fitted whole gate in there as well, but as an desertcart prime customer I didn't have to worry about this cost with next day delivery would highly recommend. ## Features - Warning:To be used under the direct supervision of an adult - 21 CM EXTENSION FOR HAUCK SAFETY GATES: This metal extension is compatible with the white stair gates for baby by hauck such as the Clear Step, Autoclose N Stop, Open N Stop, Stop N Safe 2 etc. - PRESSURE FIT: Just like the hauck baby gates, the baby gate extender is also installed by pressure fit after being connected to the gate you want to extend - DIFFERENT OPENING WIDTHS POSSIBLE: All hauck child gates for stairs and doors can be extended with a maximum of two extensions (of either 9 cm and/or 21 cm). one stair gate extender per side - COMPATIBLE WITH HAUCK Y-SPINDLE: The stairgate extension is also compatible with the hauck Y adapters, so that it can be installed on stair railings with round or oval bars up to a diameter of 10 cm - 9 CM ALSO AVAILABLE: If you are looking for a smaller stair gate extension, we recommand the hauck 9 cm baby gate extension which is also available as an accessory for the hauck safety gates ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NFW6I6K | | Age Range Description | Kid | | Best Sellers Rank | 12,629 in Baby Products ( See Top 100 in Baby Products ) 345 in Door & Stair Gates | | Brand | hauck | | Brand Name | hauck | | Closure Type | Spring | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 5,316 Reviews | | Global Trade Identification Number | 04007923596920 | | Item Dimensions W x H | 21W x 77H centimetres | | Item Type Name | Extension | | Item Weight | 0.26 Kilograms | | Item weight | 0.26 Kilograms | | Manufacturer | Hauck UK Ltd | | Manufacturer Part Number | 4007923596920 | | Material | Metal | | Material Type | Metal | | Model Number | 4007923596920 | | Mounting Type | Pressure Mount | | Mounting type | Pressure Mount | | Product dimensions | 21W x 77H centimetres | | Target Species | Human | ## Product Details - **Brand:** hauck - **Colour:** White - **Item weight:** 0.26 Kilograms - **Material:** Metal - **Product dimensions:** 21W x 77H centimetres ## Images ![21 cm Extension for Safety Gate Open N Stop, Clear Step, Autoclose N Stop 2, Metal (White) - Image 1](https://m.media-amazon.com/images/I/51b3ZPs27UL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits Perfectly — Great for Wider Spaces *by D***N on 8 May 2025* Really pleased with this extension — it did the job with no hassle and kept the gate just as secure as before.
