Screw-in anchors are installed by hand using a cross bar (not included) to screw them into the earth like a corkscrew. Unlike a tent stake, these anchors are installed at an angle so that the eye of the anchor points toward the tower and the helix screws in away from the tower.

Made of galvanized steel, these anchors are corrosion-resistant and easy to install. They provide good holding power in a variety of soil types.

6” Screw-In Anchors are included in the following kits:
