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.

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, provided the:
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.
