decorative 3-piece corner system
accessories installation
Step 1
A water-resistant material should be
used to flash the inside and outside
wall corners a minimum of 10" on
each side before installation of the
3-piece corner system (Fig. 1).
Step 2
Place the Decorative Corner Starter
on the outside wall corner, allowing a
1/4" gap between the top of the post
and the eave or soffit, and extending
3/4" below the siding starter strip.
Cut to length (Fig. 2).
Position a nail at the top of the
upper full slot on both sides of the
Decorative Corner Starter, leaving
a 1/32" gap between the nail heads
and the corner post nailing hem.
The Decorative Corner Starter hangs
from these nails. The balance of the
nailing should be in the center of the
slot, 8" to 12" apart, again leaving
1/32" between the nail head and the
Decorative Corner Starter. This allows
for proper expansion and contraction
clearance. Make sure the Decorative
Corner Starter is installed vertically
straight and true.
Do not nail corner post tight.
Step 3
For typical installations, cut two
3-1/2" or 5" Window & Door
Surround lineals to the same length as
the Decorative Corner Starter. Snap
the locking side of a Window & Door
Surround into one side of the receiv-
ing lock section of the Decorative
Corner Starter (Fig. 3). Repeat the
procedure for installing the other
Window and Door Surround.
Step 4
Make sure that all 3 parts are fully
locked and line up evenly at the top
and bottom. Fasten the Window &
Door Surround lineals to the wall fol-
lowing the same nailing procedures
outlined in Step 2 (Fig. 4).
