The system utilizes a C-Shaped Drift Headed Rail and distinctively designed Drift Rail Clips that rotate into position for easy installation. The Drift Headed Rail is a C-Shaped Drift Rail with nelson studs welded at 8" o.c. for a cast-in-place applications. For mechanically fastened applications refer to the DR-97 Drift Rail. The Drift Rail Clips use Proprietary Deflection Screws for attachment to the wall studs and allows for 3" vertical deflection (1-1/2" up and down) and is also designed with 1/8" holes to rigidly attach wall studs. ClarkDietrich deflection clips include our proprietary deflection screws that has been specifically designed to provide friction-free deflection. These fasteners eliminate drag, binding or resistance that can often occur with common fasteners.

Installation
Installation:Design load capacities for cast-in-place installations are tabulated in the product Design Guide and include:With the Drift Headed Rail embedded in the concrete structure, the Drift Clips can be positioned as required:The framing stud web must contact the flat face of the long leg of the Drift Clip.Note that one of the four slots in the channel portion of the Drift Clip is longer than the others.Tilt the Drift Clip and position it so that the longer slot initially engages one leg of the Drift Rail.Rotate the Drift Clip to the vertical position, engaging all four slots with the Drift Rail legs.Connection between the Drift Clip and Framing Studs:For bypass connections, Proprietary Deflection Screws are placed through each slotted hole of the long leg, of the Drift Clip to the web of the stud.The required number and location of the slotted holes used to secure the stud is determined by the required design load capacity.For rigid connections, self-drilling screws are placed through the pilot holes around the perimeter of the long leg of the Drift Clip to the web of the stud. To restrict clip lateral movement (Drift) along the Drift Rail, install one of two types of stops:Drift Locking Angle (DRLA) is an L-shaped clipThe long leg is inserted into the channel of the Drift Rail Clip, − The short leg is secured to the flange of the Drift Rail with a #10 self-drilling screwDrift Locking Clip (DRLC) is a C-shaped clipThe DRLC sits within the channel of the Drift Clip, and straddles the flanges of the Drift Rail.The two outside legs of the DRLC are secured to each flange of the Drift Rail with a #10 self-drilling screw.
