Installation guideDepending on application and on thickness ofboards, the CD main carriers have to be fastenedwith hangers to the slab with a distance of 1.250 mm on centres.Metal anchors, expansion bolts, have to be selectedto suit the type of slab. The distance betweenhangers and CD carriers depends on the thicknessof the boards. (See table 1)Wherever CD carriers have to be connected to eachother, CD connectors have to be used to achieve aproper connection. All abutments of CD carriershave to be staggered, and to be secured withhangers to the slab in a distance of max.100 mmfrom each connector. CD cross sections areconnected to the CD main carriers with one levelcross connectors. The plasterboards are fixed to

the CD carriers with self tapping screws Black Star® type 1, or similar. The maximumdistance between the screws is shown on table 1.Wall alignments have to be executed according tothe details of “Wall Alignments”. To achieve a firerated construction, the wings of the crossconnectors have to be bent down. If the ceilingweight exceeds 0,24 kN/m2, the wings have to befastened to the CD carriers with self tappingscrew type LN 3,5�9 mm. In case the load isexceeding 0,4 kN/m2 also the SYTRA rigid –hangers have to be fastened with these LNscrews to the CD carriers. In case access panelsare integrated in this type of ceiling, the details of data sheet 9.1/D113, 9.2/W112 “Access Panels”have to be respected.
