• For a door with a lip, as shown in Figure 9, do not
bend back the tabs on the template. Instead, position
the horizontal dotted line at the top of the lip. This
provides proper vertical placement of the holes.

• Position the template horizontally to match up the
centerlines of the header bracket and the template.
Refer to Figure 8 or Figure 9, depending on your door
style.
• To check, place the extension arm on the trolley into
the slot on the template. The extension arm should be
straight and in line with the garage door operator rail.
Note: The door arm should extend about 13mm (1/2")
over the top of the door (Figure 10 or Figure 11). If
not, check template and hole positions.
• Select and mark the (2) template holes which will allow
the mounting screws the best possible support in the
door, (preferable hole locations into the door's main
bracing) as shown in Figures 10/11. If possible, use
additional screws.
The garage door may require additional bracing to
provide suitable support.
