Valley Truss Clip

Specifically designed to provide an effective connection allowing valley trusses to be connected to common trusses. The VTCR eliminates the need to add a support wedge under the valley truss or to bevel the bottom chord to match the roof pitch. Site-adjustable, this single peice solution can be used on roof pitch angles from 10° to 40°.

  • Install VTCR with all specified fasteners:  3.35x65mm round wire nails into the supporting truss and 3.75x30mm square twsit nails into the valley truss
  • Position the VTCR onto the supporting truss and install the 3.35x65mm nail at an angle of 45º through the dome nail holes. (Fig 1)
    • Note:  when the supporting truss is 35mm thick, a portion of the nails will be exposed before penetrating into the side of the truss (Fig 3)
  • Bend the  uppper flange of the VTCR to the required angle; position the valley truss against this leg and install the 3.75x30mm nail into the bottom chord of the valley truss (Fig 1)
  • Install a VTCR on each of the top chords of the supporting trusses at each intersection of supporting truss and valley truss
