Grabbing Power

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! 

See the complete test chart here

GroundGrabba Commercial Pro II (GR14UL). These are vertical load tests 

Still not sure which GroundGrabba to use? Contact us 1300988655 or use this form.

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.
