Head-of-wall drift and deflection for exterior curtain wall and interior, nonload-bearing walls
ClarkDietrich Drift Head-of-wall clips are used in deflection conditions for in-fill curtain wall assemblies and/or interior nonload-bearing partitions to provide for both vertical (deflection) and lateral (drift) movement.
ClarkDietrich Drift Head-of-wall clips are used in deflection conditions for in-fill curtain wall assemblies and/or interior nonload-bearing partitions to provide for both vertical (deflection) and lateral (drift) movement. These clips are used in place of, or in combination with, deflection track.
The Drift Head-of-wall clips can be attached to the underside of structural members, concrete decks or floor assemblies. Structural attachments are positioned in the center of the slot to allow building drift. The "C" shaped end of the clip is slid inside of the structural stud and not fastened allowing for vertical deflection. Studs must be cut less than full height to enable vertical movement up to 2" (1" up and down).

Installation:
The Drift HOW clips come in two designs. The DHOW-LG (light gauge) is designed to be installed in structural stud gauges 33mils (20ga), 43mils (18ga) or 54mils (16ga). The DHOW-HG (heavy gauge) is designed to be installed in 68mils (14ga) or 97mils (12ga) structural studs. Attachment to the primary structure can be made with 1/4-14 screws, or concrete anchors and shall be driven through the slotted holes and positioned in the center of the slot to allow building drift. To ensure slip, back-out the fasteners about 1/2 turn. The "C" shaped end of the clip is slid inside of the structural stud and is not fastened, which allows for vertical deflection. Drywall screws (in the stud) shall be placed no closer than 4" from the slotted leg of the clip.
