Simpson Strong-Tie, a leader in engineered structural connectors and building solutions and an SFIA member, 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 … is the most versatile angle for attachment to concrete in the market.”
“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.”

Simpson Strong-Tie has introduced the RCA-C rigid connector angle.
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.
