Pinnacle hollow core anchors are designed to be drilled in and grouted through, leaving a steel reinforced grout column and anchor head in each borehole. These anchors can be installed in any condition and are ideal for conditions that would normally be difficult for conventional solid bars. Pinnacle self-drilling anchors are available in a wide range of sizes. Pinnacle offers hollow bars in both “R” (round) and “T” (trapezoidal) thread design.

Pinnacle also offers hollow bars in both steel and fiberglass. Fiberglass bars are both light and strong, and also offer a solution where corrosion protection is a concern. Fiberglass bars are also considered “diggable”, and therefore are also a good option where future excavation of in ground anchors by utility companies and municipalities is a concern.
