The US Weight 40lb Umbrella Base is a heavy, UV‑stabilized outdoor stand that secures patio umbrellas and fits poles from 1.3" to 1.76".

This compact, American-made umbrella base offers weighted stability without bulky visuals. Molded from a UV-resistant polymer, the low-profile 16.48" square footprint and 5.9" stem provide reliable support when paired with a patio table or used solo on decks and patios. Built to resist fading and surface damage, the base balances weather durability with a clean, modern appearance that blends into most outdoor settings.

How does this base keep my umbrella steady?

The 40-pound weight anchors umbrella poles so light winds are less likely to tip your setup. A threaded support knob locks the pole in place, while the stem accommodates a range of pole diameters for a snug fit. Use with your patio table for extra resistance against gusts.

• Support knob secures pole to prevent wobble
• Fits pole sizes 1.3" to 1.76" for universal compatibility
• Low-profile dimensions: 16.48" × 16.48" × 2.85"

Will it stand up to sun, rain, and seasonal use?

Yes — the body is constructed from UV‑stabilized polymer designed to resist color fade and surface brittleness from sun exposure. The synthetic material won’t rust, dent, or corrode like metal, and it wipes clean easily after outdoor use. Proper storage in extreme winter weather will extend overall life.

What pole sizes and table setups are compatible?

How simple is assembly and everyday use?

The lightweight handling for a 40 lb piece allows repositioning when necessary, while still delivering the mass needed for stability. Regular cleaning takes just a wipe-down with mild soap and water.
