URS: Titen HD® Rod Coupler Screw Anchor for Concrete Foundations

The Titen HD® rod coupler screw anchor is designed to be used in conjunction with a single or multi-story continuous rod tie-down system. This anchor provides a fast and simple way to attach threaded rod to a concrete stem wall or thickened slab footing. Unlike adhesive anchors, the installation requires no special tool, cure time or secondary setting process; just drill a hole and drive the anchor.
