> For each new course, position the first Shingle-Strip anywhere in the course.

> Align the left edge of the first Shingle-Strip in each course with the Edge Guide in the previous course (12" offset).

> Continue installing Shingle-Strips to the left and right, working toward the corners.

If the course crosses a window, door, etc., align the first Shingle-Strip on the other side with the previous course.

> To install partial Shingle-Strips (cut-offs), position the section so the numbers in the overlapping rulers are continuous.

When properly installed, all keyway joints between shingles will be offset at least 1-1/2" over 3 courses.
