BRIDGING AND BRACING

EasyClip™ USeries™ CLIP ANGLE
ClarkDietrich EasyClip™ U-Series™
clip angles are used to secure
U-channel to wall studs for lateral
bridging or for miscellaneous rigid
connections. U-channel is passed
through the stud knockout and an
EasyClip U-Series clip is screw-
attached or welded to provide
a rigid connection. These clips
are prepunched for faster, more
accurate fastener placement. Do
not use in bridging applications
when the stud width exceeds 6."

DIAGONAL TENSION STRAPPING/SHEARWALL BRACING
ClarkDietrich diagonal tension
strapping, combined with gusset
plate components, provides
shearwall (racking restraint) for
light-gauge, load-bearing framing
under wind and seismic loads. Straps
should be positioned diagonally in
an X-configuration from the bottom
to top track—on both sides of the
wall. At a minimum, double studs
at the ends of the X-brace serve as
compression studs, which must be
anchored to the foundation.

*20 and 18 gauge are 33,000psi yield strength. 16, 14 and 12 gauge are 50,000psi yield strength.
Caution: Racking loads are first transferred to the roof/floor decking and then to the
shearwalls (X-bracing). The X-bracing relies on a proper foundation to resist uplift and shear
forces. For the system to function properly, the load path from the roof or floor deck, to
the shearwalls, to the foundation must be complete.
FLAT STRAPPING
Properly spaced horizontal steel
bracing provides resistance to stud
rotation and minor axis buckling
under wind and axial loads. Block
and strapping is typically used
when wall studs exceed 6." Field cut,
blocking is used if knockouts do not
align. It’s also used as bridging when
framing members are unpunched.
