INSTALLATION
Installing Round Cuts on Gable 
Ends
Round cuts can be installed directly 
onto Cedar Dimensions Shingle 
panels. If desired for transitions, 
panels can be installed using Starter 
strip over Drip Cap, or into T-Channel 
or Lineals. When installing into 
any channel or lineal, cut 4˝ from 
the bottom of the Round Cuts 
(see Figure 18). Allow ¼˝ gap 
for panel movement.
NOTE: PANELS MUST BE 
INSTALLED FROM RIGHT TO 
LEFT. Do not nail tight. Allow ¼˝ 
into all channels, posts and stops. 
Make a template for gable angle by 
locking a short piece of siding into the 
gable starter course. Hold a second 
piece against the gable finish trim. 
Mark angle on first piece and cut 
(see Figure 19). Make templates as 
needed.
Centering Round Cuts on Gable 
Ends
When installing Round Cuts in 
gables, the last piece should be cen-
tered at the peak of the gable for 
proper appearance.
a. For symmetrical appearance at 
peak, position and lock full panel   
in the first course with Round Cuts at 
center of the gable (see Figure 20). 
Temporarily fasten through center 
hole. Continue temporarily installing 
full panels toward right side of the 
gable (see chart, Figure   
21, for overlap).
b.  When less than full panel is need-
ed, measure top of Nail Hem into   
gable end trim, less ¼˝ (see Figure 
22). Use this dimension (L) to cut   
first piece for installation.
c. To locate the cut mark on 1st 
panel, measure from the appropriate 
temperature mark to the right and 
mark top of Nail Hem (see “L”on 
Figure 23).
d. Use template and cut at mark. If 
needed for secure installation, move 
the mark an equal distance (X on 
Figure 20) from any Alignment Line.
e. Remove temporarily nailed panels.
