The Simpson Strong-Tie® RCKW rigid connectors have been developed to resist overturning moment at the base of exterior kneewalls and parapets as well as interior partial-height walls. These connectors offer a unique anchor-hole pattern that permits anchorage to both concrete and structural steel, with the larger hole designed to accommodate 1/2″-diameter concrete screws such as the Simpson Strong-Tie Titen HD®. 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.
- Use all specified screw fasteners. To achieve tabulated load values, use #12-14 screws according to the screw patterns shown.
- 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 3 exposed threads.
- Use all specified anchors. To achieve tabulated stiffness values, the installation torque for 1/2″-dia. anchors shall be at least 17 ft.-lb.
- When using the 1/2″-dia. Simpson Strong-Tie Titen HD® anchor, the bottom track must be pre-drilled or punched with a 3/4″-dia. hole.
NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
