Disclaimer:
The snaptable offset chart and ruler are intended to provide an approximate starting
point for the correct angle calculation on a given roof. Every roof is different and adjustments will
be necessary to account for construction variables. Swenson makes no warranty as to the suitability
of a particular ruler setting to achieve the correct roof slope. Likewise, the cut angle and width of
the hem are entirely dependent on accurate measurements by the operator and test cutting to
assure proper fit on the roof.
1. Select column on top representing the panel coverage width in inches.
2. Select the slope of the roof in the left column.
3. Match row and column to find the offset required on the SnapTable ruler for
the angle desired.
4. Move notcher pointer to the calculated offset number on the SnapTable ruler.
5. Bump notchers as necessary to correct for construction variations affecting
the angle of cut.
