The LTA2 is an embedded truss anchor for grout-filled CMU and concrete walls that develops high loads with shallow embedment. Designed for 2x4 minimum truss chords, the LTA2 resists uplift and lateral loads parallel and perpendicular to the wall with a minimum heel height requirement.
Simplified design of the embedded portion allows for easy positioning close to rebar
Ideal for anchoring trusses running perpendicular or parallel to the wall
Embedment line stamped on part simplifies installation and helps avoid installation errors
Galvanized; see Corrosion Information
Use all specified fasteners; see General Notes.
Hurricane ties do not replace solid blocking.
Whether in grouted CMU or concrete, the LTA2 must be embedded to the depth of the embedment line stamped on the part.
Attach to grouted concrete block with a minimum one #5 rebar horizontal in the top lintel block.
For parallel-to-wall applications, install the LTA2 with flanges facing the center of the wall. Minimum edge distance of 1 1/2" required.
Concrete applications are based on
f'c = 2500 psi.
CMU applications are based on fully
grouted CMU with an f'm = 1500 psi.
CMU and concrete applications require
one (1) #5 rebar minimum.
Loads have been increased for wind or
seismic loading with no further increase
allowed; reduce where other loads govern.
The gable end wall should be braced
to either the roof or ceiling diaphragm.
Additional connectors may be required.
BCSI Lateral Load Limits
The Truss Industry (WTCA and TPI) places
the following general limits on shear load
transfer through the truss. Trusses are
permitted to transfer load in the F1 direction
from the roof sheathing to the wall below,
per the BCSI - B8 Summary Sheet,
Distance between diaphragm
and wall (a.k.a. truss heel height)
is no greater than 6"
Trusses are spaced no greater
than 24" o.c.
Horizontal shear load transfer
is no greater than 50 plf
Trusses that do not meet all the conditions
above must resolve the lateral load transfer
between the diaphragm and the wall by
using blocking or some other means.
