Product Description
The Simpson Strong-Tie DSSCB48-KT25 is a 4 in. x 8 in. Bypass Framing Drift Strut Connector engineered to anchor cold-formed steel bypass framing to the edge of a floor slab while accommodating horizontal building drift. Designed for panelized construction, the DSSCB simplifies installation by allowing installers to set finished panels while working directly off the top of the slab - eliminating the need to predrill or preinstall anchors for each clip. This also removes the coordination challenges typically associated with pre-anchorage of standard bypass clips. With both prepunched slots and round holes, the DSSCB is a dual-function connector suitable for both slide-clip and fixed-clip applications. Each kit includes 25 connectors and 110 precision-manufactured shouldered screws, and is made in the United States from 12-gauge, 50 ksi steel with a G90 galvanized finish for lasting corrosion resistance.
Key Features
- Full 1 in. deflection range: Prepunched slots provide a full 1 in. of both upward and downward deflection, accommodating building movement without compromising structural integrity.
- Precision shouldered screws included: Precision-manufactured shouldered screws, provided with DSSCB connectors, are designed to prevent overdriving and to ensure the clip functions properly.
- Compatible with multiple strut channels: Works with 7/8-in. and 1-5/8-in. strut channels; common manufactured brands are Unistrut, PHD and B-Line. Struts are not supplied by Simpson Strong-Tie.
- Generous standoff distances: The maximum slide-clip standoff distance is 3-1/8 in. for 7/8-in. struts, 3-7/8 in. for 1-5/8-in. struts, and 2-1/4 in. for concrete inserts.
- Flexible strut anchoring options: Depending on the application and the designer's specifications, struts can be either mechanically anchored, welded, or cast in place.
- Assembly-tested design values: Tabulated design values are based on assembly testing to mitigate risk for designers, engineers, and architects.
- Heavy-gauge steel construction: Made from 97 mil (12 ga.), 50 ksi steel for high-strength performance in demanding framing applications.
- G90 galvanized coating: Galvanized (G90) for corrosion resistance in interior and protected exterior environments.
- Convenient kit quantity: Sold as 25 connectors per box, ideal for project-scale purchasing.
