Choose a low-profile square plate when the umbrella plan calls for a 100-pound galvanized-steel foundation under a table or in a freestanding layout.
Select the stem for table or freestanding use and confirm the plate is approved for the exact umbrella and site exposure. Match the base and stem to the exact umbrella, table or freestanding application, surface, and site exposure using Frankford's current base guidance. Base weight does not make an open umbrella storm-safe; close and secure the umbrella during high or sudden winds and whenever it is unattended or not in use.
Use suitable lifting practices for the 100-pound plate and keep the base on a stable, level surface.
