The Hinged Base 12 with Anchor Ring measures 12” x 12” (30,5cm x 30,5cm) and has a textured, aggressive ground contact surface. It includes an anchor ring to attach anchoring straps, ratchet belts or chains and a hinged connector that allows the clevis to move through a 90 degree range of motion to find the best angle for support. It has four holes along each side for securing the base to the ground with rebar or steel pickets, and one hole on each side to secure the hinged base plate to concrete using concrete anchors.
