The Simpson DSSCB48-KT25 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. Designed specifically for panelized construction, this dual-function connector allows installers to set finished panels while working directly off the top of the slab - eliminating the need to predrill or preinstall individual anchors for each clip and removing the coordination challenges typically associated with pre-anchorage of standard bypass clips. With prepunched slots and round holes in a single connector body, the DSSCB handles both slide-clip and fixed-clip applications, and each kit ships with 25 connectors and 110 precision-manufactured shouldered screws ready for immediate use.

Key Features

• Prepunched slots provide a full 1 in. of both upward and downward deflection - gives the assembly the vertical movement range needed to absorb building drift without stressing the framing connection.
• Precision-manufactured shouldered screws included - designed to prevent overdriving and ensure the clip functions as intended, reducing installer error and callbacks on the job site.
• 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 specifiers and contractors flexibility in sourcing strut material.
• Dual slide-clip and fixed-clip functionality - a single connector handles both applications, reducing the number of different parts that need to be stocked and tracked on site.
• Struts can be mechanically anchored, welded, or cast in place - accommodates a range of structural attachment methods depending on project requirements and designer specifications.
• Tabulated design values based on assembly testing - provides designers, engineers, and architects with verified load data to reduce risk during the specification and approval process.
• Made from 97 mil (12 ga.), 50 ksi steel with a G90 galvanized finish - heavy-gauge construction and zinc galvanized coating deliver the structural strength and corrosion resistance required for long-term performance in building envelope applications.
• Simplifies panelized construction workflow - installers work off the top of the slab without predrilling or pre-anchoring each clip, accelerating installation and reducing coordination requirements between trades.

Why This Product

• Eliminates costly pre-anchorage coordination - because the DSSCB allows finished panels to be installed from the top of the slab without predrilled or pre-anchored clips, it removes one of the most time-consuming scheduling dependencies in cold-formed steel bypass framing projects.
• One connector, two functions - the combination of prepunched slots and round holes in a single 12-gauge connector means the same part covers both slide-clip and fixed-clip conditions, simplifying purchasing and reducing on-site inventory.
• Kit includes everything needed to start fastening immediately - 25 connectors and 110 shouldered screws ship together, with screws specifically engineered to prevent overdriving so the clip performs exactly as tested and specified.
• Engineer-ready with assembly-tested load data - tabulated design values derived from assembly testing give structural engineers and architects verified numbers to work from, reducing specification risk and streamlining project approvals.
