STEP 2
Set each GBC on top of the
double top plate so that the
bend line slots are flush
with the inside edge of the
double top plate. Install
fasteners into the top of the
double top plate.
STEP 3
Bend GBC legs (one time
only) over the inside of the
double top plate and install
fasteners.
STEP 4
Install fasteners into the
gable brace.
NOTE: Attach the other end
of the gable brace to blocking
at the roof diaphragm as
directed by the Designer.
The GBC provides a proven, tested connection for the anchorage of
building stability bracing to the top of the gable end wall. With allowable
bracing installation angles between 40° to 60°, the GBC offers greater
flexibility in a connector rated for both tension and compression loads.

2. Loads have been increased 60% for wind or earthquake loading with no further increase allowed;
reduce where other loads govern.
