摘要

The object has an angle profile (B) fastened to a groove in such a manner that acrylic glass plates (C) are inserted in front of a plate that is screwed on a box (A), where a light space below an angle amounts to 3.2 millimeter. The angle profile changes the light space for inserting a 5 millimeter strong acrylic glass, pure glass and thin materials. The groove has a depth that is selected in such a manner that the plates are not plunged into a housing in an engaged condition.
