This is a special installation type. The receiving side of the roll curtain is screwed to the wall (screws are not included), and the storage side is attached to the stair posts with parts. I used it on the posts of the handrails on both sides, but the tension type would come off if I pushed it a little, so there were almost no options because there was no wall on the stairs, but the handrails were too thin to tension! This is the type for such situations. Installation post height: 88cm Roll screen height: 80cm Width: MAX 127cm The gate is a roll screen. The lock is released by pressing and turning the knob, allowing the screen to be put in and out. If a child removes the screen without releasing the lock, a loud scraping sound will be produced, letting you know that it has been released. There are some slight sunspots and stains (see images), but since it was mostly just attached, there is no feeling of use, and I can recommend it.
