safety baby gate for stairs (Leigh)

White metal gate. Comes with all screws and fastening parts. Some are probably not original. It was fastened securely to a timber frame. For mansonry wall different screws may be better. I'm sure easy to get those in diy stores. On the photo already after I unscrewed it. Previous house owner used to keep dogs downstairs. Width 75cm, but it seems adjustable. Height 68cm. Depth 3-4cm.
