Our updated base is designed to have two parts: a strong umbrella holder and a resin base. This type of construction ensures better stability and firmness. The pole of this patio umbrella stand is adjustable in diameter from φ1.5"-1.9", which allows umbrellas of different sizes to fit in perfectly. In addition, the petaloid hand-turn knob makes it easy when tightening or loosing. Thanks to its lovely design it can be used in multiple places, such as gardens, patios, terraces, balconies, barbecue bars and so on.
