Installation Instructions

VERTICAL SIDING INSTALLATION

At the peak of the gable, drop a chalk line perpendicular to the starter

strip. To determine where to start the ﬁrst panel – measure from chalk

line along the starter strip in units of 5" (127 mm) until you get to a

point where the measurement to the J-channel is less than 5" (127 mm).

Mark that point with a pencil. Measure back toward the center of the

gable from that point 1-1/4" (32 mm), and draw a vertical line, parallel

to the line dropped from the gable peak. This line is the position of the

edge of the nail hem on the ﬁrst panel.

NOTES

Measure the ﬁrst panel, cut and

install. Install subsequent panels,

increasing in length as the peak

rises. Every 3 panels be sure to

check for plumb and also measure

to the center chalk line to ensure

that you are going to arrive at

the peak with a center groove in

line with it. Make needed small

adjustments by pushing the panels

“in” or “out” within the lock. The

lock should face away from the

general viewing area.
