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.

Holding Power & Soil Types

Class 6 Soil

Definition: Loose to medium dense fine to coarse sand; firm to stiff clays and silts; dense hydraulic fill; compacted fill; residual soils

Class 7 Soil
Rated @ 2,500 lbs

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.

I understand two of the measurements on this: 3/4" is the diameter of the shaft, 66" is the length, but what is the 6" in the measurement?
1 Answer
6" is the size/diameter of the actual helix end.

What are the dimensions of the eye at the top of the anchor?  Length and width of the hole?  Thickness of the metal around the hole?
1 Answer
It's hard to give a precise answer due to the contouring of the eye.  It measures approximately 1-3/8"W x 1-1/2"L on the inside.

Wanted to use them to secure my trailer.  Are they easy to cut with a bolt cutter?
1 Answer
No, they are not easy to cut.  While they are not hardened steel, like a regular security chain, they are 3/4" thick which is going to be much too large for the jaws of any common bolt cutter we are aware of.

What specific tools are required for install and do you sell those as well?

1 Answer
We do not sell the installation tools, as there are no specific tools prescribed by the mfg.  They have advised in the past that customers use a variety of tools and different equipment.  Some simply install a pipe or piece of rebar through the eye to manually twist the anchor, while some use special attachments on a skidsteer or similar piece of equipment.

Will this withstand salt water marine use?
1 Answer

These are not specifically rated for salt water but with that being said they are Galvanized to ASTM A153, Class C and we do sell quite a few into the marine industry.

from Ocean Springs, MS asked:
March 14, 2018
Will this anchor work with a 1/2" x 12" Jaw & Eye turnbuckle, which has a jaw opening of 0.55"?
1 Answer
No, in fact it's not even that close. You would likely need to use a 7/8" shackle, connected to a 1/2" shackle which would then connect to your turnbuckle. Or, you can terminate the cable directly into the anchor and use the turnbuckle at the opposite end of your cabling system, if that's an option for you.

I know nothing about this stuff but...I showed it to our geotechnical engineer and he was very impressed. We need perhaps 20 or 30 such devices and he said "look no further; just order 'em up". Packing and shipping was also well done.

Used these to anchor wood retaining wall posts that had to be anchored to rock in post bases. Edge of helix could be sharper.
  • Great solution to a unusual problem
