The GoSports Ground Anchor permanently mounts into concrete or wood decks to securely hold your outdoor umbrellas and replace large bulky umbrella stands (umbrellas not included). The set includes all hardware required for concrete or wood installation (professional installation required, instructions included). The Ground Anchor can also be anchored into stone, brick, and tile (hardware not included - consult a contractor). The installation is permanent, but the minimalistic design provides a stable base with a small 6.25 inch x 6.25 inch footprint. The Ground Anchor is compatible with round pole market umbrellas with poles up to 2.25 in diameter and the set includes two umbrella sleeves (1.5 inch and 2 inch) for a better fit with smaller umbrellas. Also can be used as a ground anchor for sunshade or light string support poles so you can upgrade your outdoor living area. The premium polymer construction is virtually indestructible and rustproof to withstand all weather conditions. GoSports Ground Umbrella Anchor Umbrella Planter | 815898027417
