The Tempo 88 lb. umbrella base is built out of galvanized steel with the EZ-lock stand for versatility and superior stability. The locking mechanism allows for quick and easy attachment and removal of the umbrella, making it convenient for setting up and taking down. It is very important to check the umbrella base weight requirement for your umbrella. Before assembly, decide on the location of the umbrella. Allow ample height to avoid damage to your umbrella during assembly and usage. Choose a location that is level and sturdy. Avoid any sloping or soft ground.
