VertiTrack® VT

VertiTrackVT
US Patents #8,181,419 & #8,683,770

Slots of Ingenuity
Flawless Screw Placement With Friction Free Movement

Introducing VertiTrack® VT, a slotted deflection track improvement allowing for vertical movement in interior walls. This unique, patented assembly enables a positive attachment between the track and stud flanges to prevent the transfer of forces into the drywall, which could cause damage and violate the fire rated assemblies.

Value

  • Integral bushing provides for quick and accurate placement without the need to back out screws.
  • Standard #8 Modified Truss-Head screws (minimum 11mm or 0.426” wide screw head) can be fully tightened.
  • Load rated, positive mechanical attachment.
  • Connection allows up to 1 ½” total vertical deflection
  • Slots are spaced at 1” centers, allowing for virtually any stud spacing.
  • Staggered guide holes in VertiTrack’s web provide for structural attachment using PAF’s or screws.
  • Exceeds cycling standards found in ASTM E 1966 and UL2079. Rated for movement types I, II, and III.

Notes:

  1. Allowable lateral load is based on lab tests with studs at 12" from end of VertiTrack VT
  2. Wall heights are calculated from allowable lateral load at top of the wall
  3. Wall stud size should be determined independently. Wall heights  based on stud strength and stiffness should be checked
  4. Attach VertiTrack VT pieces together at splice locations with a piece of a stud

Notes:

  1. Section properties and capacities are calculated in accordance with AISI-S100-07 Specification.
  2. Tabulated gross properties are based on the full, unreduced cross section of the track away from slots.
  3. Effective section properties incorporate the strength increase from cold work of forming as applicable per AISI-S100-07, Sec. A7.2.
  4. Net effective section properties are calculated at a cross section through the slot.
  5. For deflection calculations, use the effective moment of inertia (Ix). This effective moment of inertia is calculated at a stress 0.6 Fy (service load level).
  6. Properties (Iy, Sy and My)1 are based on the web element in compression while (Iy, Sy and My)2 are based on the web element in tension.
