 With the 4 pieces in place secure the
pieces together using the pre-drilled
holes and the screws provided.
 Seal around the inside corners of the
Vinyl Siding Standoff to help ensure a
weather tight installation.
 Attach the Horizontal Cap to the
Vinyl Siding Standoff. Line up the holes
in the cap with the holes in the Vinyl
Siding Standoff and secure with the (4)
long screws provided with the cap.
 Secure the Vinyl Siding Standoff to
the wall as appropriate. Depending on
the construction of your wall, different
methods of securing the standoff and
cap may be required. The Vinyl Siding
Standoff’s anges extend 2” under the
siding and can be secured to the wall
by using screws through the siding
and ange if needed.

The Counter Flashing is typically
installed before siding or stucco
is nished and helps to ensure a
weather tight penetration through
the wall. The Counter Flashing
allows stucco, or other materials,
to be nished up to the edges of
the Counter Flashing. Under no
circumstances should stucco or other
material cover Termination Cap or
air inlets. The Counter Flashing is
available in both 1-piece and 4-piece
versions.
