Install U-Bolts and Tighten Vent Rack Drive
Vent rack u-bolts prevent the vent from opening too far and tracking out of the vent rack drives. After the ridge vent is
assembled and attached and
before the cover film is installed
, install the u-bolts. There are two u-bolts for a typical
ridge vent system. Attach one u-bolt to the vent rack closest to the gearbox and the remaining u-bolt to a vent rack
near the end of the vent frame. Set u-bolts 10"-12" from the end of each rack.
