The Lindam Wall Fix Extending Metal Safety Gate is both versatile and stylish, constructed from strong steel and fixes directly to the wall - features a push to shut opening & closing system and an extra wide walk through section with no step over bar. Not all openings and doorways are straight, or consistent in size, with staircases being the main culprits. The Lindam Push to Shut Extending Metal Wall Fix Safety is perfect for awkward sizes. It flexibly extends to fit narrow openings of 64.5 cm, to wider openings of 102 cm without the need for separate extensions. Everything you need is in the box! The wall fix fitting means it is the safest solution for use at the top of stairs. It is important that you measure the opening of where you want to install your safety gate correctly. Always measure from the narrowest point, typically skirting to skirting.
