Aluminum Duckbill Anchors are easy to install and have great holding capacity for their size. Drive them in the ground vertically, pull out the drive rod, put the rod in the cable eye and pull up with both hands. The cable pulls up about the same length as the anchors. After flipping the anchors are loading on undisturbed soil, giving them their superior holding power.
We also stock blanks (without cable) so can make custom lengths, supply w/ stainless cable or add hardware on the top end of the cable.
