I ordered the grid as staircase protection for below. Well, processing leaves something to be desired. The paint is scraped off at various points. Was maybe a claimed part?!? Processing residues degrees and chips were painted over with. For the correct mounting you should already bring a little manual dexterity. The template for measuring and marking is completely useless. However, I have other anchors and screws used, since I have not really determined to get the grid with the originals. Now it's Bombenfest and served its purpose. The locking mechanism is triggi something. Open OK, close is not so nice. One must also operate the unlocking member. After so much sweat blood and water we will keep the grid. Would not even have to drill more holes in stairs and wall of a different type. Hindsight I would not buy it again. For the price just about acceptable. MfG
