The preassembled louver/collar is fastened from the outside of the building in one
assembly.

over torque), the color coordinated screw caps are snapped into place to cover the
screw fastener heads. Provide a water seal around the top & both sides edges of
the collar/wall interface, by applying an even bead of sealant caulk at the collar/wall
interface.

fastened directly to the outside wall
, as shown in
Figure 2.
