The GroundGrabba Pro I is a heavy duty screw in ground anchor stake with lightening-fast setup and pull down. The GroundGrabba Pro is the perfect addition to your camping equipment arsenal and can even be used for permanent ground anchoring. Designed not only for soft grounds, you can also use them in all but the hardest grounds...even then you could attempt their use by predrilling a ½” diameter hole using one of our masonry drill bits. Along with the masonry drill for creating pilot holes you will need a ⅝” Hex Driver Socket which comes in an optional pack along with the drill bit.
