Installing Outside Cornerposts
Flash the corners of the home by bending a 10" wide piece of
aluminum trim coil 90° so you have two 5" legs. Cover the
entire length of the corner, lapping the upper pieces over the
lower pieces.
NOTE: Traditional, fluted and beaded SuperCorners or
four piece corner systems require wider strips of coil
for flashing.
Position outside cornerpost with the top of the post 1/4" from
the underside of the eave and the bottom of the cornerpost
3/4" below the starter strip. Remove the bottom 3/4" of the
nailing flange so it will not show below the siding when
installed.
Make sure posts are straight and true before nailing.
Hang cornerposts by first positioning a nail at the top of
the topmost nail slot. Position all remaining nails in the center
of nail slots a maximum of every 8" to 10". Leave 1/8" to 1/16"
between the nail head and the cornerpost to allow the
cornerpost to move during normal expansion and contraction.
This nailing pattern is to be followed on both nail flanges of
each post.
NOTE: All SuperCorners and TrueComfort corners install
similar to standard outside cornerposts.
If posts must be spliced for high walls, you have two options:
Option 1: Cut 1" off the nailing flanges and back from the
bottom portion of the upper post. Then lap 3/4" of the upper
post over the lower post, allowing 1/4" gap for expansion. This
method will provide an obvious joint between the two posts,
but will allow water to flow over the joint, reducing the chance
of water infiltration.
