VTCR Single-Sided Valley-Truss Clip


The VTCR is a single-sided valley-truss clip that provides a positive connection between the valley truss and the supporting framing below. Installed on top of the roof sheathing, it eliminates the need to add a support wedge under the valley truss or to bevel the bottom chord to match the roof pitch.

Key Features

  • Single-sided for new construction or retrofit applications — can be installed after the valley truss is set in place
  • Accommodates pitches from 0/12 to 12/12
  • Can be installed on either beveled or non-beveled bottom chords
  • Installs with nails or Simpson Strong-Tie® Strong-Drive® SD Connector screws


  • 18 gauge


  • Galvanized


  • The dome holes assist in installing the fasteners into the supporting framing at approximately 45°

Load Tables

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

  1. Uplift loads have been increased 60% for wind or earthquake loading with no further increase allowed.
  2. Loads are based on installation over 7/16" or 15/32" sheathing. For installation over 19/32" or 5/8" sheathing, allowable uplift loads are 285 lbs. (DF/SP) and 245 lbs. (SPF/HF) when installed with nails, or 370 lbs. (DF/SP) and 320 lbs. (SPF/HF) when installed with screws.
  3. When attached directly to the supporting framing with either screws or nails, the allowable uplift for pitches less than 4/12 is 240 lbs. (DF/SP) and 205 lbs. (SPF/HF). For pitches 4/12 to 12/12, use the tabulated uplift loads.
  4. Allowable uplift loads are based on the lower of the test loads at 3/16" deflection or the ultimate load divided by 3.
  5. Southern pine allowable download is 750 lbs.
  6. Hem fir allowable download is 625 lbs.
  7. When the valley truss and supporting framing are of different species, use the lower tabulated values.
  8. NAILS: 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
  9. SCREWS: SD #9x1 1/2" (model SD9112) = 0.131" dia. x 1 1/2" long, SD #9x2 1/2" (model SD9212) = 0.131" dia. x 2 1/2" long. See SD screws.
