Simpson Strong-Tie has redesigned its RCKW rigid knee wall connector

The updated model provides a versatile two-anchor option for structural steel contractors using 1/2” or 3/8” diameter anchors, resulting in faster and more efficient installation. When combined with the RCKWS stiffener (sold separately), the RCKW system can provide additional load capacity for optimizing overturning moment resistance.

Fabricated from heavy gauge, G90 galvanized steel, the RCKW and RCKWS have three large holes for a one-anchor solution at the edge or center of slab or a two-anchor solution for applications requiring higher capacities at the center of slab. The screw holes and anchor holes in the stiffener line up with those in the RCKW clip, making fastener and anchor installation a snap.

“The redesign to include a greater variety of anchoring options answers a contractor need for greater versatility in structural steel connectors that are adaptable and easy to use,” said Simpson Strong-Tie vice president of connectors and lateral systems Sam Hansen. “Multiple install options and load solutions help simplify installations while providing required rotation resistance so buildings can meet unique load requirements.”

Features of the RCKW system include unique small and large anchor-hole patterns permit anchorage to both concrete and structural steel. The connector also includes stiffened anchorage leg flanges to provide improved overturning moment resistance. Also, additional smaller-diameter anchor holes enable attachment to structural steel with #12 self-drilling screws.

RCKWS stiffeners can be secured to the RCKW clip with screws, optimizing overturning moment resistance and stiffness.

Based in Pleasanton, Calif., Simpson Strong-Tie manufactures and provides structural connectors, fasteners, fastening systems and building solutions.
