Simpson RCKW3-R10 RCKW 3-in. Kneewall Connector Clip (Qty-10)

Key Features

• 3-in. Width: The RCKW3 includes a large single bolt hole in the center, sized for 3-5/8 in. framing.
• Stiffened Anchorage Flanges: Anchorage legs incorporate stiffened flanges, improving overturning moment resistance at the connector base.
• Large-Diameter Anchor Hole: Accommodates 1/2-in. diameter concrete screw anchors and wedge anchors, including the Simpson Strong-Tie Titen HD heavy-duty screw anchor and the Strong-Bolt 2 wedge anchor.
• Smaller-Diameter Anchor Holes: Additional holes enable attachment to structural steel using #12 self-drilling screws.
• CMU Compatibility: Attachment to concrete masonry units (CMU) can be achieved with the Titen HD or Titen Turbo concrete and masonry screw.
• Heavy-Gauge Steel Construction: Made from 171 mil (7 ga.) steel for exceptional rigidity and strength.
• G90 Galvanized Coating: Zinc galvanized (G90) finish provides reliable corrosion resistance for long-term performance.
• Quantity: Sold in a pack of 10 clips.

Installation Notes

For greater load capacity, the RCKW3S stiffener (sold separately) nests directly onto the RCKW clip. The screw holes and anchor holes in the stiffener align precisely with those in the RCKW clip, making fastener and anchor installation straightforward. Use all specified screws and anchors as required by the application.

Frequently Asked Questions

What substrates can the RCKW3 Kneewall Connector Clip be anchored to?

The RCKW3 is designed for anchorage to concrete, structural steel, and CMU. The large-diameter anchor hole accommodates 1/2-in. diameter concrete screw anchors and wedge anchors - such as the Simpson Strong-Tie Titen HD and Strong-Bolt 2 - for concrete applications. The additional smaller-diameter anchor holes allow attachment to structural steel using #12 self-drilling screws, and CMU attachment can be achieved with the Titen HD or Titen Turbo concrete and masonry screw.

What framing size is the RCKW3 designed for?

The RCKW3 features a large single bolt hole in the center sized for 3-5/8 in. framing, making it suited for standard kneewall, parapet, partial-height wall, and overhead ribbon window framing conditions at that dimension.

Can I increase the load capacity of the RCKW3, and how?

Yes. If greater load capacity is required, the optional RCKW3S stiffener can be added. The RCKWS is a heavy 171 mil (7 ga.) stiffener that nests directly onto the RCKW clip. The screw holes and anchor holes in the stiffener align with those in the RCKW3 clip for straightforward fastener and anchor installation. The RCKW clip and RCKWS stiffener are sold separately.

What material and finish is used on the RCKW3 Kneewall Connector Clip?

The RCKW3 is made from 171 mil (7 ga.) steel and features a G90 zinc galvanized finish for corrosion resistance.
