Scafild | 4-Piece Patio Offset Umbrella Base Stand,180lbs Heavy-Duty Sand Filled Patio Umbrella Base - Black

4- Plate design: Each plate is designed to fit firmly onto the crossbar of the umbrella without any extra tools or accessories. Each plate fits together perfectly for a practical and beautiful design. (note: crossbar base not included). High weight capacity: The plates can hold up to 25.3 pounds of water (per plate) or 34.2 pounds of sand (per plate) or 43 pounds of water and sand (per plate), so you can know your umbrella will stand firm all year long. After emptying the base, there are built in handles that allow you to be able to move the base easily. Watertight seal: Each plate is built with a water port and screw cap, which allows for easy filling and emptying of the base. The screw cap creates a watertight seal which reduces the evaporation of water and lengthens the time between fills. Heavy- Duty material: The base is made of hdpe material which makes it very sturdy and recyclable. The base can bear a lot of weight and is strong enough to hold your umbrella. The base is built to withstand extreme temperature and uv rays. This base will work all year long. Easy to move and connect: Each base plate has a humanized carrying handle that allows you to move it easily. When not in use, just empty the sand and move it to the storage area.
