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 cor-
ner 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 receiving 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).
