Simpson Strong-Tie Drag Strut Connectors

Simpson Strong-Tie Drag-Strut Connectors (DSC) are built to transfer diaphragm shear forces from girder trusses or beams to shearwalls, providing critical support for lateral loads in framed structures. Available in both left-hand and right-hand configurations, these connectors help maintain structural integrity under wind, seismic, and other lateral forces.

The DSC series includes the high-performance DSC5, which uses an optimized fastener layout for fewer screws, and the smaller, lighter DSC2, designed for faster installation with minimal hardware. Both versions use Strong-Drive® SDS Heavy-Duty Connector screws for reliable, code-compliant performance while simplifying installation on the jobsite.

Simpson Drag-Strut Connectors (DSC)

Simpson Strong-Tie Drag-Strut Connectors are engineered to efficiently transfer diaphragm shear forces from girder trusses or beams directly to shearwalls, ensuring your structure handles lateral loads safely and reliably. These connectors are essential for maintaining the integrity of framed buildings under wind, seismic, or other lateral stresses.

Designed for Efficiency and Strength

The DSC series includes two key variations: the DSC5, optimized for high performance with a strategic fastener layout that reduces the number of screws needed, and the DSC2, a smaller, lighter option designed for quicker installation with minimal fasteners. Both left-hand and right-hand versions are available to accommodate different framing configurations.

Installation Tips

Each connector installs using 1/4" x 3" Strong-Drive® SDS Heavy-Duty Connector screws, which are included with the product. The optimized fastener placement ensures maximum load transfer while simplifying the installation process, saving time on the jobsite without compromising structural performance.

Applications
  • Transferring diaphragm shear forces from girder trusses or beams to shearwalls
  • Reinforcing structures in wind- or earthquake-prone areas
  • Situations where reduced fastener count and simplified installation are priorities

Simpson DSC connectors combine engineered precision and practical design, making them a reliable choice for contractors who need strong, code-compliant solutions for lateral load management.

Frequently Asked Questions

What is a DSC connector used for?

It transfers diaphragm shear forces from girder trusses or beams to shearwalls, helping stabilize structures against lateral loads.

Are there left-hand and right-hand versions?

Yes. DSC connectors are available in both left-hand and right-hand configurations to accommodate different framing layouts.

Are DSC connectors corrosion-resistant?

Yes. They are built from high-quality steel suitable for indoor and outdoor framing applications.

How do I determine if I need the DSC2 or DSC5?

Choose based on the load requirements and size of the beam or truss. The DSC5 is better for higher loads or longer spans, while the DSC2 works for lighter-duty connections.

What types of structures benefit most from DSC connectors?

Timber-framed structures, multi-story wood-frame buildings, and large roof systems that require diaphragm shear transfer.
