Drift Rail (DR97) and Clip (DRC)

Codes are what ClarkDietrich publishes as available, not a promise of local stock — tell the desk the connection you have and we'll confirm what's on a shelf. A code with no sheet of its own can be generated from ClarkDietrich SubmittalPro ↗.

Installation

Installation:Install the Drift Rail to minimum 3/16-in thick steel support structure using:WeldsPAF fastenersSelf-drilling screwsInstall the Drift Rail to concrete support structure using:Expansion anchorsScrew anchorsPilot 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 FastenersHilti 1/4" KWIK HUS-EZ anchorWith the Drift Rail installed on the structure, the Drift Rail Clips can be positioned as required:The framing stud web must contact the flat face of the long leg of the Drift Rail Clip.Note that one of the four slots in the channel portion of the Drift Rail Clip is longer than the others.Tilt the Drift Rail Clip and position it so that the longer slot initially engages one leg of the Drift Rail.Rotate the Drift Rail 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 Rail 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.
