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.

Key Features

  • 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

Material

  • 18 ga. (43 mil)

Finish

  • Galvanized (G90)

Installation

  • Use all specified fasteners; see General Notes.
  • 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.
