Specifications and installation
Because its structure principle is relatively simple, it is different from other custom-made stairs, so usually this kind of ladder does not need to be measured at the door. All you need to do is to open the stair hole. Before deciding to make this staircase, you must communicate with the manufacturer in advance and open the staircase opening strictly according to the requirements, otherwise the staircase cannot be installed.
Regarding the hole, two points should be paid attention to: The first thing to note is that 8 cm of space should be reserved for the side of the hole against the wall, because the upper four corners are carried by long screws and hung upside down on the floor during installation. Yes, if there is no space left on the wall, it cannot be installed on a diagonal load; the second thing to pay attention to is to reserve a 40 cm platform in the direction of the mouth to facilitate up and down.
