US Weight 80 lb Fillable Free-Standing Umbrella Base — 14" Stem, Rust-Resistant HDPE

The US Weight 80 Pound Free Standing Fillable Umbrella Base is a durable, rust-resistant, fillable support that stabilizes patio umbrellas for everyday outdoor use.

Designed for patios, decks, outdoor events and rental setups, this fillable umbrella base delivers heavy-duty stability without permanent installation. Its high-density polyethylene shell resists UV fading and weathering, while internal hardware uses 304 stainless steel for long-term corrosion resistance. The base ships empty or prefilled and accepts sand or gravel as ballast, giving you a customizable weight solution for different umbrella sizes and conditions.

How does this base secure an umbrella so it won’t wobble?

The base uses a 14-inch stem that fits pole diameters from 1½" to 2" and tightens with two polypropylene knobs to lock the pole in place. Inside the stem a plastic post protector supports the umbrella pole so screws don’t gouge or wear the pole surface. Grade 304 stainless steel components handle tension points and resist rust over repeated use.

• 14" high stem accommodates 1½"–2" poles
• Two polypropylene tightening knobs for a secure hold
• Internal plastic post protector prevents pole damage
• Grade 304 stainless steel hardware for rust resistance

What makes this base suitable for outdoor weather and long-term use?

The shell is molded from high-density polyethylene with UV inhibitors so the finish stays stable through sun, rain and temperature swings. Unlike plated metal bases, the polyethylene body won’t dent or corrode, while the stainless steel parts maintain structural integrity where metal strength is required. The base is offered in neutral colors to coordinate with most outdoor furniture styles.

• UV-protected high-density polyethylene resists fading and cracking
• Stainless steel (304) for rust-free load-bearing parts
• Available in black, bronze, grey and white to match decor
• Durable against outdoor climates and seasonal use

How easy is it to move, fill, or store the base?

Mobility and setup are straightforward thanks to molded hand grips and a removable wheel on the underside for rolling the empty or partially filled base. It ships empty to reduce shipping weight, so you fill it onsite with sand or gravel to reach the desired ballast weight. When you need to store or reposition it, the wheel and grips simplify handling.

• Removable bottom wheel for transport and positioning
• Molded hand grips for carrying once filled or empty
• Ships empty or prefilled depending on selection
• Prefill option saves setup time for rental or high-use settings

What installation and clearance should I plan for when pairing with a patio table?

If you pair the base with a patio table, allow at least 14 inches of clearance for the stem so the umbrella pole clears the tabletop and provides proper height for shade. The 20.5" diameter footprint offers a low profile that balances stability with minimal obstruction around seating. Filling the base to the full 80-pound capacity with sand or gravel gives reliable support for typical patio umbrellas.

• 20.5" diameter footprint for stable support without bulky appearance
• 14" stem height requires 14" clearance above a table top
• Fill with sand or gravel to achieve up to 80 pounds of ballast
• Compatible with most market-standard umbrella poles

Who this is for: homeowners, event rentals, restaurants, or property managers who need a dependable, weather-resistant umbrella base that’s easy to transport and service. Choose the empty option for cost-effective shipping and onsite filling, or select prefilled when you want a ready-to-use weight. The US Weight 80 Pound Free Standing Fillable Umbrella Base is ideal when you want solid hold, corrosion-resistant hardware, and simple handling for seasonal or all-year outdoor shade solutions.
