The professional system for the concealed mechanical attachment of glass fibre concrete panels consists of MACFOX brackets, vertical profiles and horizontal rail-to-rail connector profiles.

On the back of the glass fibre concrete panels, rail-to-rail connectors are attached by means of stud anchors and they are hung in the rail-to-rail connector profiles at the construction site.
The glass fibre concrete panels are individually height adjustable by means of adjustable rail-to-rail connectors. Per element, one rail-to-rail connector is screwed to the rail-to-rail connector profile and thus secured against slipping.
