Pleasanton, Calif. — Simpson Strong-Tie, the leader in engineered structural connectors and building solutions, today introduced the WBAC wood backing steel connector designed to eliminate alignment issues and reduce installation time in connecting wood backing to cold-formed steel (CFS) studs.

Answering contractor demand for an all-in-one wood-to-CFS connector for interior and finish applications, the WBAC provides a strong, easy-to-install, versatile solution that’s ideal for heavy wall hangings like cabinets, shelves and handrails, and features a fastening pattern and unique rolled tabs engineered for extra strength and stiffness.

Fabricated from G90 galvanized steel and available in two sizes to fit 1 1/4″ and 1 5/8″ or 2″ flanges, the WBAC attaches easily to either grade lumber or 5/8″ fire-rated board, and can be used to quickly and easily attach wood components to either drywall or structural cold-formed steel studs using #8-18 modified truss-head screws.

“The WBAC provides contractors and installers with a wood backing CFS connector that delivers heavy-duty strength for heavy-duty jobs,” says Clif Melcher, senior CFS product manager for Simpson Strong-Tie. “And with multiple models to accommodate different flange widths and no predetermined spacing layout, the WBAC delivers the versatility and adaptability to keep projects on track, too.”

Extensively tested in accordance with ICC-ES AC261, the WBAC is an ideal multipurpose wood backing CFS connector for use across a wide range of CFS interior projects, including schools, hospitals and other midrise structures. Additional features of the WBAC include:

  • Simple Installation: Prepunched holes allow the same screw to be used for both wood backing and stud attachments
  • Versatile and Adaptable: Works for any stud spacing, so predetermined or typical stud spacing is not required
  • No Alignment Issues: Sight lines help guide installation for easy alignment
  • Heavy-Duty Design: Unique rolled support bottom tabs provide extra strength and stiffness
