RCKW5.5-R10 Kneewall Connector (Carton of 10pcs)
RCKW5.5-R10 Kneewall Connector

The Simpson Strong-Tie RCKW is a heavy 171 mil (7 ga.) rigid connector that has been developed to resist overturning moment at the base of exterior kneewalls and parapets as well as interior partial-height walls or overhead ribbon window conditions. These connectors offer a unique small and large anchor-hole pattern that permits anchorage to both concrete and structural steel. The single-anchor RCKW has been redesigned to have all of the same features as the previous model but with an added two-anchor option that accommodates 1/2"- or 3/8"-diameter concrete anchors. If load requires more capacity, a stiffener, the RCKWS can be added. The RCKWS is a heavy 171 mil (7 ga.) stiffener that nests onto the RCKW clip. The screw holes and anchor holes in the stiffener line up with those in the RCKW clip, making fastener and anchor installation a snap. The RCKW clip and RCKWS stiffener are sold separately.

Key Features:

Anchorage legs incorporate stiffened flanges, improving overturning moment resistance.

Large-diameter anchor holes accommodate 1/2"-diameter concrete screw anchor and wedge anchors, such as the Simpson Strong-Tie Titen HD heavy-duty screw anchor and the Strong-Bolt 2 wedge anchor.

The RCKW5.5 and RCKW7.5 have three large holes for added versatility. The center large hole is for a one-anchor solution at the edge or center of slab. The outer larger holes are for a two-anchor solution that requires higher capacities at the center of slab. In addition, two 3/8" Titen HD screw anchors have been tested in the outer larger holes for shallower embedment required conditions like fluted deck.

Additional smaller-diameter anchor holes enable attachment to structural steel with #12 self-drilling screws.

Attachment to CMU can be achieved with Titen HD or Titen 2 concrete and masonry screws.

For the RCKWS: 171 mil (7 ga.) stiffeners are secured to the RCKW clip with screws, optimizing overturning moment resistance and stiffness.

Material:

RCKW and RCKWS: 171 mil (7 ga.), 33 ksi

Finish:

Galvanized (G90)

Installation:

Use all specified screw fasteners. To achieve tabulated load values, use #1214 screws according to the fastener patterns shown in the installation illustrations.

When using the RCKWS, secure the stiffener to the clip with the specified screw fasteners. Screws must be at least 1" long and extend through the connection with a minimum of three exposed threads.

Use all specified anchors. To achieve tabulated stiffness values, the installation torque for concrete anchors shall be at least 17 ft.-lb. or the torque requirements of the anchor, whichever is greater.

When using the larger-diameter anchor holes, the bottom track must be predrilled or punched with a 3/4"- diameter hole.
