The HHETA provides an engineered method to attach roof trusses securely to concrete and masonry walls. This extra-heavy embedded truss anchor features staggered screw patterns to strengthen uplift resistance and can be used in pairs on single- and multi-ply trusses. The versatile HHETA can be installed straight or field-bent around truss or rafter members.

Key Features

  • An indented embedment line ensures accurate embedment depth
  • Load rated for wind and seismic forces

Material

  • 14 gauge

Finish

  • Galvanized

Installation

  • Use all specified fasteners; see General Notes.
  • Embedded 4" into a 6" min. concrete beam or 8" nominal grouted block wall.
  • For mislocated truss anchors greater than 1/8" but less than 1 1/2" from the face of the truss, a shim must be provided. Shim design by Truss Engineer. When gap is greater than 1 1/2", install new anchors.
  • Minimum spacing of single anchors is twice the embedment depth for full load. For closer spacing, see loads for double anchor installation.
  • In double anchor installations, install anchors with spoons facing outward and straps spaced no more than 1/8" wider than the rafter/truss width.
  • Lateral loads are limited to 54 mil (16ga.) CFS members

Load Tables

Single Embedded Anchor Installation

  1. Allowable loads may not be increased for wind or seismic load.
  2. Minimum f'c = 2,500 psi. Minimum f'm = 1,500 psi.
  3. For simultaneous loads in more than one direction, the connector must be evaluated as described in Note d, under General Instructions to the designer.
  4. It is acceptable to use a reduced number of fasteners provided that there is a reduction in uplift load capacity. Lateral loads do not apply when fewer fasteners are used.
  5. The HHETA allowable F1 load can be increased to 435 lb. if the strap is wrapped over the truss and a minimum of 12 fasteners are installed.
  6. Minimum spacing for multiple anchor installation is two times the embedment depth for full load. See Double Embedded Anchor Installation table below for loads on closer spaced anchors.
  7. Minimum edge distance is 1 1/2" for concrete and 2" masonry.
  8. Lateral loads are limited to 54 mil (16 ga.) CFS members.
  9. See Fastening Systems for more information on Simpson Strong-Tie fasteners.

  5. Install with spoons facing outward and straps spaced no more than 1/8" wider than the truss width.
  6. F1 lateral loads listed may cause an additional 1/16" deflection beyond the standard 1/8" limit where the straps are installed not wrapped over the heel as shown.
  7. Lateral loads are limited to 54 mil (16 ga.) CFS members.
  8. See Fastening Systems for more information on Simpson Strong-Tie fasteners.
