Product Description

ClarkDietrich holdowns provide a cost-effective and secure shearwall attachment method. These holdowns are used to transfer tension loads between floors or from structural members to the foundation. The two-piece welded construction is available in three sizes for optimal performance. Installation is made easy with pre-punched bolt holes. Variations with screw attachement or bolt attachement to structrual member available. Attachment to foundation/floor is through bolted anchor attachment in both versions. Installation: 1- Install the holdowns using anchor bolts or alternate anchorage calculated to resist the tension load for your specific application. 2- Use steel nylon locking nuts or thread adhesive to minimize the chance of nut spin. Anchor bolt washer is not required. 3- For the screwed holdowns, secure the CD holdown to the steel framing member by filling all the pre-punched holes with #14 self-tapping screws to achieve listed capacities. 4- For the bolted holdowns, secure the CD holdown to the steel framing member with 3/4" and 1/2" diameter bolts in the pre-punched holes per the design load table to achieve listed capacities. Field drill holes in the framing member as required to accommodate the required bolts. 5- Boundary members (back-to-back studs) shall be designed by a qualified professional. To tie back-to-back stud members together, the Designer must determine the fasteners required to bind members to act as one unit. 6- CD holdowns can be welded per Designer's recommendation and specification. 7- Welding procedures shall be qualified as specified in AWS D1.3. 8- Welded connections used for cold-formed steel structural members in which the thickness of the thinnest connected part is 0.18 inch or less shall comply to AISI S100-2016 w/ S2-20 specification Section J2.
