SingleFix Pro is Schletter's direct fastening system for self-supporting trapezoidal sheet roofs and manufacturer-approved sandwich panels, combining Schletter Pro rails with individual SingleFix Pro fastening elements for both vertical and horizontal module mounting.
Rather than fixing through to the roof's structural substructure, SingleFix Pro clamps directly onto the raised corrugation of the roof sheet, offering a simple, fast fastening option where substructure penetration isn't practical or where sandwich panel condensation risk needs to be avoided.
