Suspended support, U-profile with continuous perforation on 3 sides and welded head plate, system HU 5050/..., for brackets for one-, two- and three-sided installation. In order to prevent the deformation of the suspended support profile when installing the bracket, the suspended support spacer profile HDS 50.50 F with hexagon screw must be taken into account for static reasons. When attaching the bracket to the suspended support profile on one side, the closed side of the bracket should preferably be aligned with the profile web of the suspended support. For static reasons and to enable the protective cap to be fitted without problems, the bracket must be mounted at a distance of x=50 mm (bottom edge of the bracket to the end of the suspended support), above the end of the suspended support. For use in functional maintenance or for suspended ceilings with fire protection requirements (model cable system guideline MLAR 2/2015), please observe additional regulations!
