Installation Guide

Step 4
With the Window Header Base securely fastened to the wall,
attach the Window Header by snapping it into place. See Figure
5 at right.
Fig. 5
Note:
Figures 4A & 4B at right show cross sections of the Window
Header in place. In some instances the Window Header may
rock on the high point of the siding. To overcome this problem,
insert the screws or Shutter Loks into the wall evenly. See Figure
4A at right. Insert the screws or Shutter Loks evenly, working
between top and bottom.

Step 3
Center the Window Header Base over the
window and spaced 1/8" above the window
trim. Use the elongated slots in the Header
Base and attach the base to the house using
the screws provided. Alternatively, the
preferred method is to use Shutter Loks.
The raised portions of the Header Base with
the round holes receive the Shutter Loks.
Attach Shutter Loks by drilling 1/4" holes into
the wall. Be sure not to fasten the screws or
Shutter Loks too tightly to allow for
expansion and contraction. See Figures 3A
and 3B at right.
