The PetSafe Anchor Kit for the wire Dog Kennels are made to hold it down and keep it in place. The anchor kit will also keep your pet from being able to move it. It is recommended that the Anchor Kit is used when the Sunblock top is installed on the wire dog kennels to keep it from blowing over. The Anchor Kit works with all wire kennels and it only requires simple hand tools to put it in. It comes with four aluminum anchors with galvanized wire cables.
