OCTAGONS + SCALLOPS APPLICATION
Prior to installation: Find the center of the
gable or wall so that shapes will be visually
centered. For best nished appearance,
gable installations should end with a single
Scallop or Octagon at the peak.
STRAIGHT WALL APPLICATION
• Begin by measuring the length of the
wall between the corner trims.
• Next, divide length of wall by two to nd
the center of the wall.
• Mark the center of the wall.
• The easiest layout for the Octagons or
Scallops to be visually centered on the
wall, is to start so that a keyway lands
over the center of wall mark.
• Calculate the layout of full panels from
the center mark and make a mark on the
wall (full panels measure 48").
• Measure from the trim to the mark so
that siding section ts against corner
board, with a 3/16" gap.
• Trim left side of a panel to t and begin
installation.
GABLE APPLICATION
• Start by dropping a plumb line to nd
the center of the gable. Mark this line.
• Next measure the height of the gable
(in inches) on this line. For Octagons
divide by 9-5/8". For Scallops divide by
7-3/4".
• The purpose of this simple equation is
to nd out the number of courses or
rows.
• Then, divide the height of the gable by
the size of the exposure of the prole
that will be installed.
• Example: 64" gable height with scallops.
(64"÷ 7.75" = 8.25 - Eight is an even number, do
not worry about the decimal, center on a keyway
to start.)
• If the answer is an even number, center
the rst course of Scallop or Octagons
on a keyway.
• If the answer is an odd number, center
the rst course on a Scallop or Octagon.
• Begin by locating the rst piece relative
to the centerline of the gable. The panel
may be positioned anywhere along its
length, as long as the keyway or shingle
face is centered.
