Key Features

Built for Overturning Loads

This Simpson Strong-Tie RCKW7.5-R10 kneewall connector clip is made to resist overturning moment at the base of exterior kneewalls, parapets, and interior partial-height walls. That matters when the connection at the slab has to do real structural work, not just hold parts in place.

Three-Hole Anchorage Options

The RCKW7.5 layout gives you a center hole for a one-anchor setup and outer holes for a two-anchor setup when the design calls for more capacity. That gives the installer more flexibility without changing connector families.

Multi-Surface Attachment

Large and small anchor holes let this clip work with concrete anchors, structural steel fasteners, and CMU anchor options. For cold-formed steel framing crews, that makes one connector useful across more jobsite conditions.

Overview

The Simpson Strong-Tie RCKW7.5-R10 Kneewall Connector Clip is a heavy-duty rigid connector for cold-formed steel construction. This is a kneewall connector clip designed for resisting overturning moment at the base of exterior kneewalls and parapets as well as interior partial-height walls. Model Number: RCKW7.5-R10. If you are tying light-gauge wall framing back to concrete, structural steel, or CMU and need a connector built for engineered load paths, this is the right category of hardware.

What sets the RCKW7.5 version apart is its three large anchor-hole pattern. The center hole supports a one-anchor solution at the edge or center of a slab, while the outer holes support a two-anchor solution when higher capacities are needed at the center of slab. That gives designers and installers more flexibility with the same connector, especially on jobs where slab location and anchorage demands vary from one condition to the next.

This connector is made from 171 mil 7 gauge steel with a G90 galvanized finish. In plain terms, it is a thick, structural-grade clip with corrosion protection suited to its intended construction use. The anchorage legs incorporate stiffened flanges to improve overturning moment resistance, which is exactly the kind of detail that matters on kneewall and parapet work where the base connection takes serious force.

The hole pattern is also practical in the field. The large-diameter anchor holes are sized to accommodate 1/2 inch concrete screw anchors and wedge anchors, including Simpson Strong-Tie Titen HD heavy-duty screw anchors and Strong-Bolt 2 wedge anchors. Smaller-diameter anchor holes allow attachment to structural steel using #12 self-drilling screws. For CMU applications, the connector can be used with Titen HD or Titen Turbo concrete and masonry screws. That kind of cross-application flexibility can simplify material selection for crews working across different substrates.

For projects that need more capacity, Simpson Strong-Tie offers the RCKWS stiffener, which nests onto the RCKW clip. The stiffener lines up with the clip’s screw and anchor holes, so it adds stiffness and overturning resistance without forcing a completely different installation approach. Just note that the RCKW clip and RCKWS stiffener are sold separately.

This connector makes the most sense for engineers, framers, and contractors working in cold-formed steel framing, especially on exterior kneewalls, parapets, ribbon window conditions, and interior partial-height walls where the base connection is part of the structural design. It is not generic bracket hardware. It is a purpose-built Simpson Strong-Tie connector for specific engineered wall conditions.

Flexible Anchorage for Real Job Conditions

This connector is built for attachment conditions that do not always look the same from one wall section to the next. The hole layout gives you options for one-anchor or two-anchor setups depending on the slab location and capacity requirement.

• Three large holes on the RCKW7.5 provide added anchorage versatility
• Outer-hole two-anchor setups are intended for higher-capacity center-of-slab conditions
• Stiffened flanges at the anchorage legs help improve overturning moment resistance

Heavy Steel Construction Without Guesswork

There is nothing light-duty about this connector. The thick steel body and corrosion-resistant finish are what you want in a base connection that is part of the structural design, not an afterthought.

• Made from 171 mil 7 gauge steel
• Galvanized G90 coating helps protect the connector in typical construction environments
• Optional RCKWS stiffener can be added when the design requires more capacity

Built For

Cold-Formed Steel Framing Exterior Kneewalls Parapet Walls Interior Partial-Height Walls Ribbon Window Conditions Commercial Construction General Contracting Structural Wall Connections

Pro Tip

If you are using the larger-diameter anchor holes, predrill or punch the bottom track with a 3/4 in. hole before you start setting anchors. It saves rework and keeps the installation moving once the wall is standing.

Tool Nut’s Take

Tool Nut’s Take

Simpson Strong-Tie RCKW7.5-R10 Kneewall Connector Clip Gets Specific for a Reason

This is the kind of connector you buy when the base of the wall actually matters structurally and you do not want to fake it with generic hardware.

• Who it’s for: Cold-formed steel framing contractors, engineers, and commercial crews building kneewalls, parapets, and other partial-height wall conditions.
• Why it stands out: The three-hole anchorage layout gives you more than one installation path, and the 171 mil 7 gauge build is clearly made for engineered load demands.
• Worth knowing: This is a 10-pack of clips only. Anchors, screws, and the optional stiffener are not included, so make sure your fastening package matches the design.

Common Questions

• What is this connector designed for? It is designed to resist overturning moment at the base of exterior kneewalls and parapets, as well as interior partial-height walls and overhead ribbon window conditions in cold-formed steel construction.
• Can it be used with concrete anchors? Yes. The large-diameter anchor holes accommodate 1/2 in. concrete screw anchors and wedge anchors, including Simpson Strong-Tie Titen HD and Strong-Bolt 2 anchors.
• Can it attach to structural steel or CMU? Yes. Smaller holes allow attachment to structural steel with #12 self-drilling screws, and CMU attachment can be achieved with Titen HD or Titen Turbo concrete and masonry screws.
• Is there an option for added capacity? Yes. The optional RCKWS stiffener nests onto the RCKW clip and aligns with the existing holes for added stiffness and overturning resistance.
