The MGT is a connector designed to resist moderate uplift loads in masonry applications that are typically installed prior to roof sheathing. This medium girder tiedown allows flexible installation, with options to install the straps either vertically or wrapped over the top of the truss. The MGT can be anchored down into place directly into CMU.

Load Tables

MGT/HGT Load Table
  1. Attached members must be designed to resist applied loads.
  2. Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
  3. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  4. To achieve the loads listed for the MGT, install SET-XP® anchoring adhesive anchorage into a 8"-wide concrete tie-beam or grouted and reinforced CMU tie-beam with a minimum embedment depth of 12". Vertical reinforcement may be required to transfer the loads per designer. Alternate anchorage may be determined by designer.
  5. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  6. The MGT can be installed with straps vertical for full table load, provided all specified nails are installed to either a solid header or minimum double 2x6 web.
  7. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
