SlickBlue 4-Piece 13L Cantilever Umbrella Base Black

4-Piece Cantilever Umbrella Base

This black HDPE base set is designed for cantilever offset patio umbrellas. It suits homeowners who need a stable, modular ballast that can be moved around a deck or garden. The four plates stack together when the umbrella is not in use.

13-Litre Per Plate Water Capacity

Each plate holds 3.4 gallons or 13 litres of water, and up to 5.2 gallons of sand for extra weight. Filling all four plates gives the total ballast required to keep a large offset canopy steady in wind.

Easy-Fill Spouts and Hidden Handles

Integrated spouts let you pour water or sand without splashing, while concealed handles make each 17.5-pound plate simple to lift and position. Circulation holes add friction on smooth surfaces, and the plates stack flat for compact storage.
