Snergytec's Railless metal sheet mounting system facilitates the rapid mounting of framed PV modules on trapezoidal metal sheet roofs with minimum thickness 0.8mm, only 4 components are required to install the modules directly to the roof. A base mounting clip is 100mm – 140mm long, therefore easy to carry and attach to almost all trapezoidal and sandwich roofs. The EPDM sheet is in the package to seal the screw against the metal sheet.
