Maximum Depth. Maximum Grip. Minimal Fuss.
The 615mm GroundGrabba Pro II 12-Pack is our deepest GR13 anchor—purpose-built for serious ground hold in sand, clay, or soft soils where shorter stakes just won’t cut it. Whether you’re securing large tarps, fencing, shelters, jumping castles, or gear in unpredictable terrain, these long anchors deliver the confidence and staying power you need. Trusted by tradies, event crews, commercial rental operators, and seasoned off-roaders alike, this is your go-to for deep bite anchoring power.
Engineered for Demanding Environments
When Longer Really Does Mean Stronger
At 615mm long and fitted with a wide 35mm flight, the Pro II is designed to penetrate deeply and generate serious resistance to pull-out. Its extended shaft and coarse flighting make it ideal for environments where sand, mud, or soft clay challenge traditional tent pegs or lighter anchors. It’s galvanised, heavy-duty, and ready for the harshest conditions—whether you're setting up for a weekend or a week-long operation.
Built for Professionals, Campers & Contractors
Need to hold down something big—something expensive—something that can’t afford to move? These are the ground screws you want. Each anchor features a 16mm hex head for fast drill-powered install, saving time and eliminating the struggle of hammering spikes. From commercial marquee hire to off-grid camps and beach shelters, the GroundGrabba Pro II has earned its place as the heavy-lifter of the GR13 family.
