Multiple sizes and capacities allow precise design and load match for all applications. The table above displays a complete selection of Helical Anchors available for the utility industry. Helical ground anchor leads are available in lengths from 3' (1M) to 10' (3M). Helix diameters range for 6" (150mm) to 14" (355mm) in both 3/8" and ½" thickness. Multiple helix combinations, situated on the same shaft, allows designer to target ideal load bearing soils and formations. Helical ground anchor extensions are also available in 3' (1M) to 10' (3M) lengths with a forged coupling for quick precise connection. Various termination connectors are available to secure the guywire to the ground anchor from threaded thimble eyes to clevis applications.

Corrosion protection is provided in the form of hot dipped galvanization (per ASTM A123). Hot dipped galvanization is a great choice for protection from the elements giving design professionals the assurance of long term performance. This added protection allows for installation in aggressive soils and wet areas alike; see our Design and Technical Service Manual for full corrosion information.
