The 2.8 cm spacer sleeve is a base sleeve that lets you maintain the distance between the wall and the sliding system. It is adapted to doors with a thickness of 3.5-4 cm and to our Smart sliding systems.
With a door thickness of 4 cm, most Smart sliding systems maintain a distance of 1.5 cm between the door and the wall. This is a sufficient distance for standard skirting boards. However, if your skirting board is more than 1.5 cm deep, you should purchase an additional spacer sleeve. With thinner doors, the wall distance becomes larger.
The number of spacer sleeves required depends on the number of holes in the guide rail.
