The Simpson Strong-Tie RCKW 5.5" Kneewall Connector Clip (Model RCKW5.5-R10) is a heavy 171 mil (7 ga.) rigid connector engineered to resist overturning moment at the base of exterior kneewalls and parapets, as well as interior partial-height walls or overhead ribbon window conditions. Sold in a convenient quantity of 10, this G90 zinc galvanized clip delivers robust, corrosion-resistant performance and accommodates anchorage to both concrete and structural steel through a unique dual anchor-hole pattern.

Key Features

• RCKW5.5 has three large holes for added versatility - the center hole is for a one-anchor solution at the edge or center of slab; the outer holes are for a two-anchor solution that requires higher capacities at the center of slab
• Anchorage legs incorporate stiffened flanges, improving overturning moment resistance
• 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
• Additional smaller-diameter anchor holes enable attachment to structural steel through use of #12 self-drilling screws
• Attachment to CMU can be achieved with Titen HD or Titen Turbo concrete and masonry screw
• Width: 5 1/2 in.
• Made from 171 mil (7 ga.) steel
• Galvanized (G90) for corrosion resistance
• Quantity: 10

Frequently Asked Questions

Can the RCKW5.5 be used with both concrete and structural steel?

Yes. The RCKW5.5 features a unique small and large anchor-hole pattern that permits anchorage to both concrete and structural steel. Large-diameter holes accommodate 1/2-in. concrete screw anchors and wedge anchors, while additional smaller-diameter holes enable attachment to structural steel through use of #12 self-drilling screws.

What options are available if a higher load capacity is needed?

If load requires more capacity, the optional stiffener model RCKW5.5S can be added. The RCKW5.5S is a heavy 171 mil (7 ga.) stiffener that nests onto the RCKW clip, with screw holes and anchor holes that line up with those in the RCKW clip for easy fastener and anchor installation. The RCKW clip and RCKWS stiffener are sold separately.

How many anchor solutions does the RCKW5.5 support?

The RCKW5.5 has three large holes for added versatility. The center hole provides a one-anchor solution at the edge or center of slab, while the outer holes support a two-anchor solution for applications requiring higher capacities at the center of slab.

Can the RCKW5.5 be attached to CMU (concrete masonry units)?

Yes. Attachment to CMU can be achieved using the Titen HD or Titen Turbo concrete and masonry screw anchors.
