Commercial Ground Anchor Pack – 2 x 450mm GroundGrabba Pro (Lighter Duty Fixings)

• 1 Pack of 2x GroundGrabba Pro Commercial (450mm)

How They Work

The 450mm GR14 Commercial GroundGrabba is the shortest in our heavy-duty GR14 range, designed for strong hold in firm or compacted ground without the need for concrete or traditional methods.

Its wide, sharp auger flight cuts deeply into the earth, creating an anchor point that resists uplift and lateral movement. Installed with a high-torque impact wrench, this anchor is ideal for securing temporary structures, site infrastructure, or industrial equipment where a reliable, removable fixing is required.

The GR14 shaft is thicker and the hex head larger than our general GR13 series—purpose-built for commercial-grade performance where strength, speed, and reusability matter.

How They Work

This currently is our entry level Commercial product.  Our Industrial commercial earth ground anchor earth range GR14 works by penetrating the ground and forming an inverted conical kind of shape of earth holding grip in the ground. 

If exposed to extreme lifting forces, unlike ground anchors that are threaded along the complete length of the shaft that catastrophic fail, our augur designed earth anchors will lift in a controlled failure way, usually giving advanced notice before failing as the augur section still needs to haul its way through the earth that is compacted on top. 

 Essentially compared to our general GR13 range, the shafts are thicker, the hex heads are larger and lengths are 450mm, 600mm and 900mm.

*GroundGrabba Commercial GR14 Series have been certified in accordance with AS4100 and A2159

Hold Down Capacity 

In our tests, we have found that if we compare same length spike stake to a GR14 of the same length and girth, then the difference ranges from around X3 to X7 in holding power!

IMPORTANT***Please note that these figures are a guide only.  The results are vertical lift absolute momentary peak readings and you should allow a decent safety margin.   Ground types vary. Through the depth of one ground anchor the ground can be of different densities therefore different anchoring characteristics.    These all rely on correct deployment.

Recommended Tools to hire or own to help with installation: 

NB. These models were available at the time of writing.

For driving these into the ground, we recommend a high-torque impact wrench. Consider models like:

For driving these into the ground, we recommend a high-torque impact wrench. Consider models like:

• Makita 40v TW001GZ-40v Brushless 3/4" Impact Wrench.
• Milwaukee M18 FUEL 2867-20
• Use a masonry drill at least the same length as the GR14 you choose for pilot holes in harder ground.

Important Note:

GroundGrabba Commercial range is designed for heavy-duty use with a tradie quality heavy-duty impact wrench.

Please note that these are not toys. Ensure you have a powerful drill, especially for hard ground conditions.
