JULY 2025

8. The final panel will need to be
cut to fit the remaining area. Cut
panel 1” wider(Prolok rib height) than the

remaining area and fold up 1” to match
the Prolok ribs, and provide a bench for the
gable trim to sit on.

NON-VENTED RIDGE
9a. Once panels are completed

the next step is to install
closure strips along the top
of the panels. After closures
are complete, install Z Bar

in the 1.5” space left between
the ridge and the panels.

VENTED RIDGE
9b. Once panels are completed

the next step is to install
profile vent clips, 1 per ft.
Fasten the clip on the bottom
only to start. Bend up the front
of the clip to slide in the profile

vent. Then fasten down the top
of the clip. The top of the clip
should line up with the top of

the panel.
