Product Description
The Simpson Strong-Tie RCKW 7.5-in. Kneewall Connector Clip 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. Fabricated from 7-gauge steel with a G90 zinc galvanized finish for lasting corrosion resistance, this connector features a unique dual anchor-hole pattern - accommodating both small and large anchors - that permits secure anchorage to concrete, structural steel, and CMU. With stiffened flanges on the anchorage legs and multiple anchor configurations, the RCKW7.5 delivers versatile, high-capacity performance in demanding structural applications. This listing includes a quantity of 10 clips.
Key Features
- Three large anchor holes for versatility: The center hole provides a one-anchor solution at the edge or center of slab; the outer holes support a two-anchor solution for higher capacities at the center of slab.
- Stiffened anchorage leg flanges improve overturning moment resistance for demanding kneewall and parapet applications.
- 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.
- Additional smaller-diameter anchor holes enable attachment to structural steel using #12 self-drilling screws.
- CMU attachment can be achieved with Titen HD or Titen Turbo concrete and masonry screws.
- 7 1/2-in. width for kneewall connector applications.
- Heavy 171 mil (7-gauge) steel construction for rigid, reliable structural performance.
- G90 zinc galvanized coating provides corrosion resistance for interior and exterior applications.
- Quantity of 10 clips included per pack.

Frequently Asked Questions
- What types of surfaces can the RCKW7.5 be anchored to?
- The RCKW7.5 is designed for anchorage to concrete, structural steel, and CMU. The large-diameter anchor holes accommodate 1/2-in. diameter concrete screw anchors and wedge anchors - such as the Simpson Strong-Tie Titen HD heavy-duty screw anchor and the Strong-Bolt 2 wedge anchor - for concrete applications. The additional smaller-diameter anchor holes allow attachment to structural steel using #12 self-drilling screws. For CMU, attachment can be achieved with the Titen HD or Titen Turbo concrete and masonry screw.
- What is the RCKWS stiffener, and is it included with this product?
- The RCKWS is a heavy 171 mil (7-gauge) stiffener that nests onto the RCKW clip to provide greater load capacity when the application requires it. Its screw holes and anchor holes align with those in the RCKW clip for straightforward fastener and anchor installation. The RCKWS stiffener is sold separately and is not included in this listing, which contains only the 10 RCKW7.5 clips.
- What are the three large anchor hole configurations on the RCKW7.5, and when would each be used?
- The RCKW7.5 features three large anchor holes to offer installation flexibility. The center hole is intended for a one-anchor solution at either the edge or the center of the slab. The two outer holes are used together for a two-anchor solution when higher load capacities are needed at the center of the slab. This configuration allows the connector to be adapted to different structural demands without requiring a different product.
- What material and finish does the RCKW7.5 use, and what applications is it designed for?
- The RCKW7.5 is made from 171 mil (7-gauge) steel and features a G90 zinc galvanized finish for corrosion resistance. It is a 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. The anchorage legs incorporate stiffened flanges to further improve overturning moment resistance in these demanding structural applications.
