Option 2: Cut a 6" length of cornerpost and trim the nail
flange, receiving channel, and sides until you have just a 90°
bend of vinyl. Using PVC primer and PVC cement, glue the
bent piece to the inside of the upper post and lower post. Butt
the two posts together. Nail the entire assembly as one post
with all nails in the lower post centered in the nail slots.
Also see additional instructions covering installation of
four-piece cornerposts (page 30).
Capping an outside cornerpost
One method of capping an outside cornerpost is to cut a
piece of J-channel twice as long as the width of the
cornerpost face. Mark a 90° angle from the center and cut
out this area. Then cut 7/8" away from each end, except for
the nailing flange. Bend the J-channel in the center and nail it
to the outside of the corner of the house. Then insert the
cornerpost into the J-channel.
Another alternative is to trim the nail flange, receiving channel,
and sides from the bottom 1" of the cornerpost. Notch 1" at
the 90° bend, fold the bottom 1" of the cornerpost face, and
fasten these “flaps” with a pop rivet.
