MGT/HGT Girder Tiedowns

MGT/HGT

The MGT and HGT series are girder tiedowns for moderate- to high-load applications that are typically installed prior to roof sheathing. The MGT wraps over the heel and is anchored on one side of the truss. The HGT straddles the heel and anchors on both sides of the truss. The HGT is field-adjustable, making it suitable for trusses with top chord slopes up to 8/12. The HGT is available in sizes for 2-, 3- and 4-ply widths.

Material

  • MGT — 12 gauge; HGT — 7 gauge

Finish

  • MGT — galvanized; HGT — Simpson Strong-Tie® gray paint

Installation

  • Use all specified fasteners; see General Notes
  • When the HGT-3 is used with a 2-ply girder or beam, shimming is required and must be fastened to act as one unit
  • Attach to grouted concrete block with a minimum one #5 rebar horizontal in the top lintel block
  • MGT — Install a minimum of (6) 10d nails into the face of roof member that is on same side as MGT base

Load Tables

  1. Attached members must be designed to resist applied loads.
  2. Minimum f'm = 1500 psi and f'c = 2500 psi.
  3. To achieve the loads listed for the MGT and HGT, anchorage into a 8" wide concrete tie-beam or grouted and reinforced CMU tie-beam can be made using Simpson Strong-Tie® SET-XP® anchoring adhesive with a minimum embedment depth of 12". Vertical reinforcement may be required to transfer the loads per Designer.
  4. Allowable loads have been increased for wind or earthquake loading; no further increase allowed; reduce where other loads govern.
  5. 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.
  6. NAILS: 10d = 0.148" dia. x 3" long. See other nail sizes and information.
