Abstract
A box for a system for opening and closing a communication route between two separate areas, the system including separation means suitable for allowing and preventing, respectively, at least partially, crossing of the route by light, may include: a box body configured to accommodate a movement unit of the system; and support elements for the movement unit. The box body may have a major extension direction. The box body may be defined by support and closing profiles, both extending along the direction. The support profile may define at least one upper, lower, and connecting wall. The closing profile may define a closing wall. The closing profile may be removably fixable to the support profile for closing the box body. When the closing profile is fixed to the support profile, a distance between the closing wall and the connecting wall may be less than or equal to 20 millimeters.
