Ensure your parasol is always held firmly in place with this umbrella base. Made from strong HDPE plastic, the thick shell is made to be used outdoors, the surface also wipes clean from any dirt and mess. Weighs 28kg or 40kg after filling with water or sand - both can also be mixed - so it keeps weighted down to the ground. Side hold to fill and empty easily. Note: Holds 38mm and 48mm size parasol poles, with tightening screws to hold steady. Please measure your umbrella pole diameter in advance to make sure our umbrella base fits your umbrella well.
