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.

At what angle do you recommend to bury/ xxxx -in the anchors?

6 years ago

The manufacturer specifies "...the anchors must be installed in the direction of the guy load and installation must be within 5 degrees of alignment of the guy load.

What size hook and eye turnbuckle fits this anchor?

6 years ago

Unfortunately, none really fit it directly. We did a test fit with a 1" size and it was close, but did not quite fit. The sizes above and below did not fit either. The mfg. recommends using a 5/8" shackle as an adapter between the anchor and your turnbuckle. Otherwise, you will need a jaw turnbuckle with a 2" jaw opening, which will be quite large.

How do these deal with rocks in the ground?  If I get 4ft down and run into a rock do I have to start over?

6 years ago

Essentially, yes. You should not expect the anchor to bust or otherwise move the rock for you. If you're using a Bobcat or similar piece of equipment with an attachment, and you can install the anchors with greater force and speed, it will likely be less of an issue.

What is the max diameter shaft that can fit through the eye?

10 months ago

We were able to coax a 1-1/4" pin through the eye. It was tight, but it went.

When affixing a single guy wire to a triple eye anchor, which "eye" position would be best? Middle? Does it matter for anchoring performance? Or am I just being picky about the aesthetics?

3 years ago

We're not aware of any specific guidance on this, but in general, a load that is centered is always preferred. If you can center the cable and still have good vertical alilgnment with the direction of the load, that is ideal.

Can you recommend a wire to go along with this to secure a large leaning tree?

5 years ago

We really can't specify a cable from here. We simply do not have all of the information needed, and we do not offer engineering services. Having said that, the normal holding strength of this anchor is 11,000 lbs, which means that 3/8" Galvanized Cable should be sufficient. If you want to step up to something more robust, that will stretch a little less, you could consider 1/2" Galvanized Cable, or even 1/2" 1x7 EHS. One thing to keep in mind is that EHS cable is very stiff and generally requires termination using Big-Grip or Tree-Grip dead ends. If you use regular 7x19 or 6x19 cable, you can terminate it much easier using regular cable clamps, thimbles, etc. You will likely want to incorporate an inline turnbuckle with your setup too so that you can take up… See full answer »

I plan on anchoring a 40 foot container on each corner and pouring 20 inches thick concrete with the shaft of the anchor running through the concrete and then welding a plate of steel to the shaft then welding the container to the plate. The anchor would be going straight down. Would this work?

4 years ago

It's a bit of an engineering question, and these were really designed to hold in soil, so we can give only a qualified yes, we think your solution will work fine.
