Adjustable Quick-Lock® Unibar® Centralizer — 10–11-in. O.D., #6–#18 Rebar Size (16-Qty) by Simpson Strong-Tie

The revolutionary Simpson Strong-Tie® Quick-Lock® Unibar® centralizers are the answer to threaded-rod, rebar and tendon alignment support in earth-retention applications. They keep the rod, bar or tendon centered in the bore/drill hole to allow for minimum grout/concrete coverage and do not impede flow of grout within bore/drill hole. The adjustable centering device will accommodate single bar, single and multi-strand anchors, encapsulated anchors (DCP), and are suitable for steel or plastic pipe applications. The adjustable Unibar installs quickly by simply snapping the two identical halves over the rod, bar, or tendon, and securing with tie-wire or zip ties. The end tabs are offset to fit between rebar threads.
