Our patent-pending Quick-LockTM UnibarTM Centralizer is the answer to uniform reinforcement steel spacing requirements in single-bar foundation/tieback elements. They allow for minimum grout/concrete coverage and do not impede flow of grout within bore/drill hole and around tendon. Assemble quickly by simply snapping the two inverted identical halves together over the tendon/rebar and tying it on with tie wire, or with a zip tie threaded through the end tab slots.

To achieve proper design strength in any drilled and grouted/concreted hole, the tendon/rebar or anchor material must be centered in the shaft to allow minimum coverage throughout the length of the element. Our Quick-LockTM UnibarTM Centralizers are made of durable, noncorrosive plastic and are designed for a variety of applications where concrete cover must be maintained.

Building a strong foundation is only a few clicks away! Our quality products and ease of installation allows you to save time and money on the job site. Imagine the infinite opportunities to use Quick-LockTM UnibarTM Centralizer.
