Maximum Hold When You Need Maximum Certainty

The 900mm GroundGrabba Commercial Pro II is built for big jobs—like securing containers, tiny homes, and structures exposed to extreme conditions. It drills deep into sand, clay, or unstable soil with confidence. Powered by your impact wrench and a 1” AF socket, this is the anchor of choice when failure is not an option.

Maximum-Strength Ground Anchoring System

When Everything Depends on Staying Put

The GroundGrabba Commercial Pro II delivers unparalleled holding power with its extended 900mm (3ft) shaft design. Field-proven during extreme weather events—including cyclones—these heavy-duty anchors provide critical security for portable buildings, site sheds, and valuable assets where failure simply isn’t an option.

Engineering That Outperforms

Our legendary auger technology creates a deep, inverted conical earth grip that dramatically outperforms standard anchoring methods. Unlike conventional threaded anchors that can fail without warning, the GroundGrabba Commercial Pro II features controlled-failure technology—providing early warning signs before maximum stress is reached, giving you time to act.

Ideal Applications:

  • Portable buildings & site offices ("dongas")
  • Relocatable homes & modular structures
  • Mobile homes
  • Shipping containers & storage solutions
  • Industrial equipment & machinery
  • Solar panel arrays & renewable installations
  • RVs & caravans during extreme weather
  • Construction site infrastructure
  • Temporary roadways & access solutions
  • Heavy-duty signage & barriers

The GroundGrabba Advantage:

  • Maximum penetration – 900mm shaft creates superior holding power in all soil types
  • All-terrain performance – Works in sand, dirt, clay, rocky ground, and even snow
  • Industrial-grade materials – 15mm shaft and reinforced hex head withstand extreme force
  • Quick install – No concrete required, install in minutes with common power tools
  • Reusable – Fully recoverable and reinstallable
  • Lifetime warranty – Built to last, backed for life

Trusted in the Field

“I recently purchased GroundGrabba Commercial 900mm Pro II's to hold down a number of our site sheds. We just experienced Cyclone Alfred and I’m super pleased to say our sheds didn't budge. I also like the fact these are reusable.” – Russell B.

Each pack contains TWO heavy-duty Commercial Pro II anchors, giving you matched pairs for balanced, reliable securing.

Based on real-world use in cyclone zones—no lab tests, just serious results.
