STEPS
1. Starting on the left hand side, at the eave of the building (looking eave to peak), align the
Floating Rake Angle flush with the existing rake angle. It is critical that the Floating Rake Angle
be straight and square with the building as it controls the alignment of the roof panels.
2. Fasten the Floating Rake Angle with #12-14 x 1 1 /
4
" Shoulder Self Driller screws into the center of
each slot, (12" intervals). Do not overfasten screws. Movement of Floating Rake Angles are
imperative for proper installation of the system.
3. If two or more Floating Rake Angles are required, butt ends of Floating Rake Angles (do not
overlap) and continue fastening.
4. If necessary, field cut Floating Rake Angles to terminate 12" from peak of building.
5. Install Floating Rake Angles on the opposite end where the panels terminate using the same
procedures as before.
6. After applying Floating Rake Angles, insulation (if required) can be installed. Roll out insulation
eave to peak, laying side of insulation on Floating Rake Angle.
7. Avoid sidelap of insulation occurring directly beneath sidelap of panel.
