The Multi-Trapezoidal Bracket MTH is mounted directly onto the crown of the panel, straddling the profile. No surface preparation is necessary; simply wipe away excess oil and debris, align, and apply. Secure through its pre-punched holes, using the approved Hexagon Bi-Metal drilling screws with sealing washer. To ensure brackets are installed in a straight line, install a single Multi-Trapezoidal Bracket MTH each end of the roof at a measured, consistent distance from the bottom edge of the roof. Use a string line between the two brackets. Mount the remaining Multi-Trapezoidal Bracket MTH along the string line, directly into the sheeting of the trapezoidal rib of the roof.
