Product Description

These heavy-duty earth anchors are used for securing poles, tower, trees, stages and other similar structures. We sell them into the arborist, tower rigging and stage rigging industries. They are popular because they are both strong and economical, and install easily. Simply turn/screw the anchor into the ground using a strong bar placed through the anchor's forged eye. No special tools required--may be installed by hand, or with machine power. Designed with a forged triple eye rod with an angled point and a firmly welded helix. A hot-dip galvanized finish meets ASTM Specification A153, Class C for long resistance to rust.

Anchor requirements are site specific. Soil type should be determined to ensure that the correct anchors are used. Always seek professional guidance. Anchors must be installed at an angle of 45º in the direction of the load. Failure to install within 5º of alignment of the guy load will significantly lower strength. Capacity ratings apply to properly installed anchors only.

* Holding strengths are approximate and based on industry standards. Determining soil load capacity is an inexact science limited by an inexact environment, from all of the unknowns both below and above the surface of any anchoring application--the soil medium, installation method, local climate, connections to the anchored structure--no one can guarantee an exact holding strength. Load capacity is not a simple function of “soil class” but also of real-time moisture content, compaction, root penetration, installation method, pullout load angle and other factors unique to the installation’s time and place. Therefore the only way to truly determine holding strength is on-site specific probing and testing.

Will this work for anchoring an eight slip boat dock?
1 Answer
Yes, there are customers using these in a marine environment.  But there are factors to consider, such as the soil type, current, etc., thus we recommend consulting an engineer or qualified contractor regarding the location, installation and number of anchors used.
