Instructions / Assembly

ClarkDietrich light-gauge C-studs for axial load-
bearing and curtain wall framing are prepunched with
knockouts at regular intervals. These punchouts are
specifically designed to allow for rapid installation of
pipes, electrical conduit and wall bridging.
Standard knockout sizing is 1-1/2" x 4" in members
3-1/2" and wider. Members smaller than 3-1/2" are
unpunched unless otherwise specified at time of
order. If specified, members will be punched with a
3/4" x 4" knockout.
Knockouts are punched 12" o.c. from the lead edge
with additional knockouts every 24" o.c. (on the
West Coast, the first knockout is punched 24" o.c.
from the lead edge). Caution must be exercised when
installing studs so knockouts align for bridging. Based
on stud length, the distance the knockout falls from
the tail end of the stud may not be the same from the
lead end. To align punchouts, make sure to use the
same end in the same direction consistently.

Grommets snap easily into stud
knockouts and are used to protect
electrical wiring and plumbing
lines from contacting metal.
Grommets are commonly used
when metal conduit is not required
by building code.
STRUCTURAL TRACK
ClarkDietrich structural track is a
U-shaped framing component used
as top and bottom runners to secure
wall studs. Structural track is also
used as end support closures for
joists at exterior or foundation walls,
head and sill plates of wall openings
and solid blocking. Track is normally
ordered in corresponding size and
gauge to the wall studs.
