Product Description
The Simpson Strong-Tie RCKW 3-in. Two-Anchor Kneewall Connector Clip (Model RCKW3D-R10) is a heavy 171 mil (7 gauge) rigid connector engineered to resist overturning moment at the base of exterior kneewalls and parapets, as well as interior partial-height walls and overhead ribbon window conditions. Its unique dual anchor-hole pattern accommodates anchorage to both concrete and structural steel, delivering reliable performance in demanding structural applications. This package contains 10 clips.
Key Features
- Two-Anchor Design: The RCKW3D features two large holes - one on each end - for increased anchorage capacity compared to single-anchor configurations.
- Stiffened Flanges: Anchorage legs incorporate stiffened flanges that significantly improve overturning moment resistance at the connector base.
- Large-Diameter Anchor Holes: Two large-diameter anchor holes accommodate 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.
- Heavy-Gauge Steel Construction: Fabricated from 171 mil (7 ga.) steel for exceptional rigidity and structural integrity.
- Corrosion-Resistant Finish: Zinc Galvanized (G90) coating protects against corrosion in exterior and demanding installation environments.
- Expandable Capacity: When greater load capacity is required, the optional RCKWS stiffener nests directly onto the RCKW clip, with screw holes and anchor holes that align perfectly for fast, straightforward installation.
- Made in the USA: Manufactured in the United States.

Frequently Asked Questions
- What types of anchors are compatible with the RCKW3D connector?
- The RCKW3D's two large-diameter anchor holes accommodate 1/2-in. diameter concrete screw anchors and wedge anchors. Compatible options include the Simpson Strong-Tie Titen HD heavy-duty screw anchor and the Strong-Bolt 2 wedge anchor. The unique anchor-hole pattern also permits anchorage to both concrete and structural steel.
- Can the load capacity of the RCKW3D be increased beyond its standard rating?
- Yes. When greater load capacity is required, the optional RCKWS stiffener (model RCKW3DS) can be added. The stiffener is made from the same 171 mil (7 ga.) steel and nests directly onto the RCKW clip. The screw holes and anchor holes in the stiffener align with those in the RCKW clip, making fastener and anchor installation straightforward. The RCKW clip and RCKWS stiffener are sold separately.
- What applications is the RCKW3D designed for?
- The RCKW3D is engineered to resist overturning moment at the base of exterior kneewalls and parapets, as well as interior partial-height walls and overhead ribbon window conditions. Its stiffened anchorage leg flanges improve overturning moment resistance, making it well suited for demanding structural connections in both residential and commercial construction.
- What material and finish is the RCKW3D made from?
- The RCKW3D is fabricated from 171 mil (7 gauge) steel for exceptional rigidity and structural integrity. It features a Zinc Galvanized (G90) coating that provides corrosion resistance, making it appropriate for exterior and other demanding installation environments.
