Simpson Strong-Tie has expanded its lineup of rigid connector angles with the addition of the RCA-C, an ideal solution for attaching cold-formed steel (CFS) stud framing to concrete supports.

Designed to save installers time and reduce the cost of drilling connector holes at the jobsite, the RCA-C provides the most anchor options available, including holes for a 1/2"-diameter anchor screw or bolt, or for two 1/4"-diameter concrete screws positioned to allow a variety of fastening options.

The Simpson Strong-Tie family of rigid connector angles include general-purpose clip angles designed for a wide range of cold-formed steel construction applications. With prepunched holes for fastener attachment, these L-shaped clips save time and labor on the job and can be used for miscellaneous header/sill connections to jamb studs, jamb stud reinforcement at track, u-channel bridging, stud blocking, bypass curtain-wall framing, joist connections and other applications.

“The RCA-C rigid connector angle for concrete is the most versatile angle for attachment to concrete in the market,” says Simpson Strong-Tie product manager Clif Melcher. “Plus, all RCA connectors have been rigorously tested and load rated, providing contractors with confidence in quality and performance for virtually any job.”

Fabricated from G90 galvanized steel for enhanced resistance to corrosion, the RCA-C is ideal for fastening stud framing to concrete supports where versatility and productivity are required on the jobsite. Additional features of the RCA-C include:

  • 2" x 2" legs for plenty of room to make attachments to structure and stud framing
  • Multiple screw pattern options for different load rating options on stud framing
  • Prepunched holes for attachment of screws to stud framing and concrete
  • A range of load applications—the connector can be used either to form a heavy-duty shear and tension connector or to form a light-duty moment connection

Prepunched holes on the RCA-C anchor leg provide options for attachment to concrete or masonry, which can be achieved with 1/2" Titen HD or Strong-Bolt anchors or 1/4" Titen HD or Titen Turbo anchors.
