The Simpson DSSCB Bypass Framing Drift Strut Connector is engineered to anchor cold-formed steel bypass framing to the edge of a floor slab while accommodating horizontal building drift. Dual-function by design, it features both prepunched slots and round holes, allowing a single connector to serve in either slide-clip or fixed-clip applications. For panelized construction, this connector streamlines the process considerably: installers can set finished panels while working off the top of the slab, with no need to predrill or preinstall anchors for each individual clip. The DSSCB also eliminates the coordination difficulties typically associated with pre-anchorage of standard bypass clips, reducing on-site complexity from start to finish.

Key Features

• Prepunched slots deliver a full 1 in. of upward and downward deflection - gives the structure genuine drift accommodation in both directions, reducing stress on framing connections during building movement.
• Precision-manufactured shouldered screws are included - engineered to prevent overdriving and ensure the clip functions as intended, removing a common installation variable that can compromise performance.
• Compatible with 7/8-in. and 1-5/8-in. strut channels - works with widely available brands such as Unistrut, PHD, and B-Line, giving designers and contractors flexibility in sourcing strut channel independently.
• Dual-function connector handles both slide-clip and fixed-clip applications - a single product covers multiple installation scenarios, simplifying procurement and reducing the number of part numbers on a job site.
• Struts can be mechanically anchored, welded, or cast in place - adapts to the anchorage method that best suits the project design, without requiring a dedicated connector for each approach.
• Tabulated design values are based on assembly testing - gives designers, engineers, and architects verified load data to reference with confidence, reducing risk during the specification process.
• Made from 12 ga., 50 ksi steel with a G90 galvanized finish - heavy-gauge construction paired with corrosion-resistant coating supports long-term durability in demanding cold-formed steel framing environments.
• Eliminates predrill and pre-anchorage steps for each clip - installers working off the top of the slab can place finished panels in sequence without stopping to set individual anchors, accelerating panelized construction schedules.

Why This Product

• Designed specifically for bypass framing drift conditions - unlike general-purpose clips, the DSSCB is purpose-built to anchor cold-formed steel bypass framing to a floor slab edge while actively accommodating horizontal building drift, addressing a structural requirement that standard connectors are not designed to handle.
• Simplifies panelized construction workflows - by allowing finished panels to be installed from the top of the slab without predrill requirements or individual anchor pre-installation, the DSSCB reduces both labor steps and the coordination burden that comes with pre-anchored bypass clip systems.
• One connector, two functions - the combination of prepunched slots and round holes means the same DSSCB unit can be used for slide-clip or fixed-clip applications, giving project teams the flexibility to adapt on the fly without stocking separate hardware.
• Included shouldered screws protect installation integrity - the precision-manufactured #14 XLSH78B1414 shouldered screws shipped with the connectors are specifically designed to prevent overdriving, ensuring the clip moves and functions correctly rather than being locked down by an overtightened fastener.
