TRAKLOC® Drywall Framing System

telescopes in length to deal with variances during installation

TRAKLOC® Steel Framing is a revolutionary development in cold-formed steel framing systems. Unlike traditional steel studs, which are cut to length for varying jobsite conditions, TRAKLOC® allows you to order one length member and “adjust” the length accordingly to make up for variances in the slab. The TRAKLOC® Stud and TRAKLOC® Track systems consists of a traditional-style framing member combined with an interlocking adjustable component. The adjustable portion allows for telescopic length adjustments and can accommodate variances in the slab, minor wall heights per floor, etc.  The interlocking component of the stud and track eliminate the need for most connections!

Installation Recommendations

Meets ICC ESR-1464  in compliance with the 2012 International Building Code® (IBC) and 2010 California Building Code (IBC)
The TRAKLOC system is Intertek Warnock Hersey Design Listed and approved for use in both one and two-hour fire-rated head-of-wall assemblies requiring deflection in accordance with ASTM E-119 and ASTM E-1966.

Features and Benefits

Another added benefit to the TRAKLOC® system is that screw attachment of the stud and track is not required. The patented swage end formation in the stud, combined with the swaged forming of the track, allows for the two members to “interlock” with no need for screw attachment. The knurling along the web of the track allow for minor adjustments to be made while keeping the members solidly locked in place. TRAKLOC® steel framing members come in standard widths of 2-1/2," 3-5/8", 4" and 6."
  • Twists and locks into place. Studs can be installed from the ground, greatly reducing time spent climbing ladders and scaffolding.
  • Installation of TRAKLOC is ICC-ES approved without the use of fasteners to attach the studs to the top or bottom track. ICC-ES Report # ESR-1464.
  • Significant productivity gains are possible versus conventional stud and track framing. This results in substantial installed cost savings!
  • Safer Framing System™ reduces jobsite hazards. Less time spent climbing scaffolds, ladders, lifts and bending over to install screws result in fewer job related injuries and reduced workers compensation costs.
  • Less cutting of studs significantly reduces material scrap and waste.
  • Less noise, less steel shavings and improved air quality.
  • Allows for seismic and live-load vertical inter-floor deflection in the stud, not the track. This feature eliminates the need for deflection tracks in fire-rated head-of-wall assemblies.

(TLE) TRAKLOC Elevator Stud™

In many retrofit conditions, one of the biggest battles is having to transport stud and track members in and out of elevators. In what we call our Elevator Stud™, the TRAKLOC® members can fully compress inside themselves and then telescope out to full length. What this means on the jobsite is that you can essentially get an 18'-0" fully extended stud in a 10'-0" elevator car. This not only saves the labor of stocking the framing but also reduces installation, as you no longer have to splice studs. The  TRAKLOC® system is versatile and can satisfy even the most difficult jobsite interior non-loadbearing condition and save you labor in the process.

How do you stock studs for framing a 16' tall wall when your freight elevator only has a 12' length capacity?

ClarkDietrich manufactures standard lengths and special order lengths, with extra long telescopic extensions, that's how.

Elevator studs can be ordered where the Stud Extension overlaps the Stud Open End by 100% when compressed and by only one foot once extended. Elevator studs do require the one foot overlap minimum once extended. 4" and 6" studs are required to have the overlap secured with four screws*. Nonetheless, a 10' (when compressed) stud could be extended up to an installed length of 19'.

*Due to the fastening of the TRAKLOC splice, elevator studs are not for deflection by themselves.

TRAKLOC TTS Track standard length is 10'-0" to accommodate a standard elevator car.  Shorter lengths are available for non-standard conditions.
