VGT and S/VGT2.5 Variable-Pitch Girder Tiedowns

VGT and S/VGT2.5

The variable-pitch girder tiedown, S/VGT2.5, is a high-capacity tiedown for single- or multi-ply CFS girder trusses. It attaches with self-drilling screws from the side of the truss. The VGT uses Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws for wood truss applications. They both feature a predeflected crescent washer that allows them to accommodate top-chord pitches up to 8/12.

Load Tables - VGT and SVGT2.5 Variable-Pitch Girder Tiedown
  1. Designer shall insure attached members are adequately designed to resist applied loads.
  2. Straight-line interpolation can be used to determine allowable loads for pitches between 3/12 and 8/12.
  3. Allowable loads on wood have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other load duration factors govern.
  4. For (min.) tabulated values, not all screw holes need to be filled. Install screws symmetrically.
  5. See more information on Simpson Strong-Tie fasteners.
