MaxTrak® Slotted Deflection Track

Performance that stands up to deflection

For superior head-of-wall vertical deflection, and the added benefit of horizontal drift movement, ClarkDietrich has your answer.

Application(s): Standard Wall, Chase Wall

For superior head-of-wall vertical deflection, and the added benefit of horizontal drift movement, ClarkDietrich introduces two solutions—MaxTrak® Slotted Deflection Track and MaxTrak® 2D Slotted Deflection & Drift Track. The MaxTrak System allows the top of the wall stud to float within the track legs. This connection allows for vertical live load movement of the primary structure without transferring axial loads to the wall studs. In addition, MaxTrak 2D also has slots in the web to allow for horizontal drift when required by seismic designs.

Construction Advantages:

  • Provides positive attachment to wall framing for overall wall strength with no additional components
  • MaxTRAK Non-Structural Systems are available with 2-1/2" legs
  • MaxTRAK Structural Systems are available in two leg lengths: 2-1/2" or 3" legs
    • 2-1/2" Leg MaxTRAK has 1-1/2" long slots with a total allowable vertical (deflection) movement of 1-1/2" (3/4"±)
    • 3" Leg MaxTRAK has 2" long slots with a total allowable vertical (deflection) movement of 2" (1"±)
  • Total allowable horizontal (drift) movement of 4" (2"±) (MaxTrak 2D only)
  • One-piece system reduces the cost of materials and labor
  • Easy installation reduces labor costs
  • Fire-rated system integrates with a variety of UL® head-of-wall fire stop systems
  • MaxTrak 2-1/2" Leg system has code report Intertek CCRR-0205
  • Can be used for both interior non-load bearing walls and exterior curtain wall systems
  • Embossed guideline at center of vertical deflection slot helps installers correctly position fasteners accurately and quickly
