Duckbill Earth Anchors are a great way to secure just about anything in your yard or garden. Keep your garden and yard features in place and protect young trees from the harsh winds of winter. Three sizes available for different holding power. All three sizes are sold each or in Tree Guying Kits. Drive Rods are available for driving the Duckbill into the ground, recommended if uses several Duckbills, otherwise a piece of rebar the length of the cable will suffice for a single Duckbill application.
