Rail system for sliding magnetic marker-chalk boards for classrooms

The system is a system of guiding rails and classroom blackboards fixed in them. Two boards have the possibility of fixing to the wall, two boards are equipped with a system of rollers and have the possibility of moving along the rails. The upper rail is fixed to the wall on a system of L-shaped brackets with a maximum distance of 200mm. In the upper rail there are brakes limiting the movement of the boards. The lower rail is fixed to the wall under the stationary boards. On the movable boards there is a bracket with a roller located in the lower part, this roller ensures the movement of the boards in one plane parallel to the wall.
