The 1617-6-18-UBC Adjustable Quick-Lock Unibar Centralizer is a sophisticated solution designed for the precise alignment of threaded rods, rebars, and tendons in earth-retention applications. It ensures the exact centering of the rod, bar, or tendon within the bore/drill hole, facilitating minimal grout/concrete coverage and unhindered grout flow. These applications are particularly well-suited for earth retention, soil nails, micropiles, and tieback projects. The versatile centering device accommodates various configurations, including single bars, single and multi-strand anchors, and encapsulated anchors (DCP), making it suitable for both steel and plastic pipe applications.
