For shutters sizes 55" and over, use six screws per shutter. For smaller sizes use four screws per shutter. See figures below right.
Step 1 Place the shutter next to the window and mark desired location against the wall or window. See Figure 1 at right.
Step 2 When installing shutters smaller than 55", drill (4) 1/4" holes in the locations shown in Figure 2A at right.
If the shutter is 55" and over, drill (4) 1/4" holes and (2) 11/64" holes in the locations shown in Figure 2B at right.
Step 3 Reposition the shutter against the wall and screw it into place using the screws provided. Do not over tighten the screws. When installing a shutter 55" and over, screw the two center screws in first (the screws using the 11/64" holes).
