MGT/HGT Girder Tiedowns

>>Home > All Products - Alphabetical List

The MGT and HGT series are girder tie-downs 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 ranging up to 8:12. The HGT is available in sizes for 2, 3 and 4-ply widths.

Material: MGT - 12 ga; HGT - 7 ga.

Finish: MGT - Galvanized; HGT - Simpson 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.
See wood applications.

top Load Table: See code report listings below

Attached members must be designed to resist applied loads.
Minimum f'_m = 1500 psi and f'_c = 2500 psi.
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 SET epoxy with a minimum embedment depth of 12". Vertical reinforcement may be required to transfer the loads per Designer.
Allowable loads have been increased for earthquake or wind loading; no further increase allowed; reduce where other loads govern.
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.
Table allowable loads were determined using tested lowest ultimate/3 or fastener calculation values.
NAILS: 10d = 0.148" dia. x 3" long. See other nail sizes and information.
