    Additional Information

    Feedback from customers who use our GroundGrabba Pro II's for more semipermanent ground anchoring of pop up garages, timber for landscaping, simple garden retaining wall use.   In these instances one needs to drill a hole in the material that is wider than the 25mm flange washer collar for the flights(spirals/wings) of the GroundGrabba to pass through.  Once the hole diameter is larger than the Hex Head and Collar there is a need for a wide washer to make the diameter of the original collar wider.  Enter the HookWasher!

    Simple and genius - perfect tie down point

    Perfect! I used these + ProII anchors + Grunt Straps to tie down a lighting setup for our wedding. I maxed out the Grunt Straps and my lever block to tension the catenary setup, and these hooks didn't even look like bending. Simple, neat, cheap, and strong-as!!

    Hi Ken,

    Thank you so much for your fantastic review on our ClosedHook tie down points! We are thrilled to hear that they were the perfect solution for your wedding lighting setup. We take pride in providing simple, neat, and strong products that withstand even the toughest tasks. We also appreciate your previous positive reviews for our other items. We hope you continue to choose our products for all your tie down needs.

    Thank you again! David and team GroundGrabba

    Secure for tiny house on wheels

    If there's one thing I learned from Cyclone Alfred, it's that I needed some serious anchorage for my tiny house on wheels, deck, and solar system which is installed on a trailer. Particularly the solar system, which is set on an angle and catches the wind like a sail. With David's guidance and deep knowledge, I used the 900mm commercial pro ground anchors, with the cable tie downs for the ratchet straps to attach to. These are so unbelievably well designed - they fit the ground anchors like a charm, and they're versatile (eg can use one loop or both loops onto the ground anchor, and can use them to splay out to multiple ground anchors to increase hold). They're also very, very, very strong. Now that everything is in place, I'm absolutely confident everything is cyclone proof. Highly recommend these cable tie downs.

    Hi Kerry, thank you for taking the time to leave such another thoughtful review. We're happy to hear that our Cable Tie Downs with Dual End Loops were able to provide the secure anchorage you needed for your tiny house on wheels, deck, and solar system. We are dedicated to creating high-quality and versatile products, and we're glad they were able to meet your needs. Thank you for choosing our products.

    Great product, incredible service

    In preparation for the recent cyclone event I needed something to anchor my caravan to the ground. I found Ground Grabba via Facebook, & called David to enquire further. The product seemed perfect for the application, & after receiving excellent advice from David, I ordered the right product online. The cyclone was predicted to hit the coast at any time, so I was keen to get them ASAP. It turned out David's business was not far from my home. As I didn't have the impact torque wrench required to drive the anchor stakes into the ground, David offered to lend me his. Not only that, but he delivered the Ground Grabbas along with the impact wrench to my home well after business-hours, & helped me install them in the wind & rain. He also lent me the ratchet straps that I also needed. The whole setup only took about 15mins, very easy to do. The cyclone came & went, & my caravan is still safely secured. I can't thank David enough for his willingness to go out of his way to help, & for producing such a great product! Highly recommended.

    Hey Jonathan,

    Thank you so much for your kind review! We are so glad that our Stainless Steel Strap Tie Downs connected to your GroundGrabba Commercial Pro I's were able to help secure your caravan during the recent cyclone event. We always strive to provide excellent service and it's great to hear that I (David) was able to assist you with everything you needed. Our team is always here to help in any way we can. Thank you for choosing Ground Grabba and for recommending us. Stay safe!

    Kind regards David Levne , inventor and co-founder
