16" Overlap
After mounting upper c-channel withproper overlap, straighten wall with string line
Once wall is straightened, screw c-channelstogether with steel stud screws or sheet metal screws
As you build the wall, install theupper exterior c-channel to help stiffenthe wall and hold everything together
Exterior c-channel
Interior of wall
Installing upper interior c-channelis the last step. This will allow
for the panels to be slid upfor access to the cavity.
After all the rebar is tied, the wall isinspected, and the bottom of the
cavity is cleaned out, thenthe interior c-channel
may be installed.

Brace and plumb back surface beforeattaching the stud of the intersecting wall
(See next page)
Use 1" sheet metal screwsspaced 12" vertically
Plumb T-intersection in all directions before screwing together
When using 8" or less wall system,rip this splice panel to the same width
as the intersecting wall cavity
Plastic stud with cut flanges
If you need a T-Intersection
When using 10" thick or larger wall system,use two equally sized splice panels with
a stud rail joining them
