HealSmart Cantilever Umbrella Base Weight Plates 4-Pack Black — 176 lb Water Capacity, HDPE UV-Resistant

The HealSmart 4-piece square base plate set secures offset cantilever umbrellas by providing up to 176 lb (water) / 132 lb (sand) of ballast in a compact, weather-resistant design.

This black four-plate kit is built for freestanding cantilever or offset umbrella cross bases that need modular weight. Each plate is injection-molded HDPE with a UV- and weather-resistant coating, a convenient spout for filling, and interlocking pins so the plates lock together around a cross-style umbrella frame (crossbar base not included). The plates stack for storage, include ergonomic handles for repositioning, and are sized for residential or commercial patios, decks, poolsides, and balconies.

How much weight does the set provide and how is it filled?

The complete set supports up to 176 lb when filled with water and up to 132 lb with sand, giving you a strong ballast option without steel weight. Each plate fills through a built-in nozzle with a screw cap for secure closure and easy draining when needed.

• 4 plates combine for maximum ballast — water or sand fill options
• Filling spouts and screw caps prevent leaks and simplify refills
• Each plate dimensions: 19.7" x 19.7" x 3" for predictable capacity

Will these plates fit my cantilever umbrella base and lock securely?

The plates are shaped to sit in a cross-style cantilever base and include interlocking pins to hold the assembly together. They were designed to integrate with most common offset umbrella cross bases to create a stable platform for the umbrella stand.

• Square plate shape fits common crossbar base designs (base sold separately)
• Interlocking pin system keeps plates aligned and resists shifting
• U-locking-compatible design for added security where the crossbar allows

How durable and weather-resistant are the plates?

Made from high-density polyethylene (HDPE) and finished with a UV- and weather-resistant coating, the plates resist fading, cracking, and impact from regular outdoor use. Their material choice keeps them lighter to move when empty but robust once filled.

• HDPE construction for impact resistance and long outdoor life
• UV-resistant coating to slow discoloration and material breakdown
• Ergonomic handles and stackable shape for easy transport and storage

How easy is it to move, store, and maintain the set?

When empty the plates are light and manageable using the molded handles; when filled they deliver steady ballast but still allow for disassembly and drainage. Cleaning is straightforward through the filling spout and occasional wipe-down of the outer surfaces.

• Molded handles for lifting and aligning plates during installation
• Stackable design reduces storage footprint when not in use
• Simple screw-cap filling and draining for seasonal removal or transport

Who is this for: The HealSmart 4-piece umbrella base plate set is suited to homeowners, café and outdoor hospitality operators, and property managers who need a modular, durable ballast solution for offset/cantilever umbrellas. It works well where heavy fixed bases are impractical or when seasonal removal, storage, or transport is required. Choose water fill for convenience and cost-savings or sand fill where added mass and permanence are preferred.
