For multiple pairs, the table values F1,Rk () must be multiplied by the factor nef = (the number of pairs)^0,9 and table value F2, Rk must be multiplied by the number of pairs. - The minimum heights of the main and secondary beams depend on angle of incline of the secondary beam and must be defined in each case. - Appropriate action must be taken to ensure adherence to the insertion angle (assembly angle) and the connection geometry. - In the case of intermediate values of angle of incline  of the secondary beam, linear interpolations may be made. - The main beam must have adequate fork support and be able to withstand torsion. All calculations must be verified and signed off by the planner in charge before the work is performed. β=90° α System WT Fastener length [mm] Minimum dimensions [mm] Installation dim.
