Drift Rail (DR97) and Clip (DRC)

Installation:

Install the Drift Rail to minimum 3/16-in thick steel support structure using:

• Welds
• PAF fasteners
• Self-drilling screws

Install the Drift Rail to concrete support structure using:

• Expansion anchors
• Screw anchors

Pilot holes are provided along the length of the Drift Rail web at a spacing of 6-in on-center.

Design load capacities for commonly used fasteners are tabulated in the product Design Guide and include:

• Hilti X-U Universal Knurled Shank Fasteners
• #12-24 HWH Fasteners
• Hilti 1/4" KWIK HUS-EZ anchor

With the Drift Rail installed on the 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.
