Downer Framing DCS004 Mechanical Secret Fix System Tech Guide

Downer Framing DCS004 Downer DCS004 Framing System is designed to provide a mechanical secret fix support to most rainscreen cladding panels using the principle of a ventilated façade. DCS004 MSF can be installed onto our DCS031 Helping Hand, DCS041 Floor to Floor or DCS021 Omega & Zed system offering design freedom to suit project specific thermal and structural demands and variation in cavity depths. DESIGN CONSIDERATIONS The ends of any DCS004 Horizontal Carrier Rail unsupported cantilever should be ≤150mm or as dictated by project specific static calculations. At building corner locations, HCR cantilever can be increased up to max. 300mm and must be strapped to adjacent HCR using an “L” rail angle such as DCS031 60×40 L rail.
