DriftTrak^® DTSL

Exterior Head Of Wall

Product Application

DriftTrak^® DTSL is available to accommodate vertical deflection and lateral drift requirements. VertiClip^® SL’s, with Step Bushings pre-installed in vertical slots, allow up to 2” vertical deflection (1” up and down). Clips are manufactured to fit into the DriftTrak and provide free lateral movement of the structure. DriftTrak is available in 12’ lengths. DriftTrak DTSL does not provide wall closure. A top track will be required for closure of the wall assembly.

DriftClip^® DTSL has been issued an
ICC-ES Report. Click here to access
ICC-ESR-2049 (pdf).
