C-Hopetree Umbrella Base 70 lb Water-Fillable Patio & Market Stand — Black, Dual-Lock Adjustable Holder

Built from recycled plastic designed for outdoor exposure, this C-Hopetree umbrella base gives a stable, low-maintenance anchor for freestanding or table-style market umbrellas. When filled with water or sand it reaches roughly 70 lb (31 kg) of ballast while remaining easy to move when empty. The base accepts 1.5" (38 mm) and 1.9" (48 mm) umbrella poles and uses a simple double-lock fastening system for reliable hold on decks, patios, and lawns.

How does this base keep my patio umbrella steady?

The base combines filled weight with a wide footprint to resist tipping from wind gusts and everyday bumps. The double-lock design pairs a rotary knob clamp with an adjustable collar to hold pole diameters securely in place.

• 70 lb (31 kg) filled ballast for improved stability;
• Wide, flat base profile lowers center of gravity;
• Rotary knob and adjustable collar prevent wobble and slippage;
• Compatible with freestanding or through-table umbrella setups.

What size pole will this stand fit and how do I adjust it?

Designed to fit two common pole diameters, the base supports 1.5" (38 mm) and 1.9" (48 mm) tubes without extra adapters. Adjustment is fast: set the pole into the tube, tighten the rotary knob, then secure the collar for a snug fit.

• Built-in holder accepts 1.5" and 1.9" poles;
• Adjustable collar adapts to pole circumference;
• Single rotary tightening knob locks the pole in place;
• No separate adapters required for the two supported sizes.

How do I fill, empty, and maintain the base?

Fill through the provided opening with water for convenient ballast or add sand for heavier, longer-lasting weight. Emptying is equally simple—open the drain cap and tip the empty base to move it — and its recycled plastic construction resists sun and rain without frequent upkeep.

• Fill hole accepts water or sand (not included);
• Drain cap for fast emptying and transport when unfilled;
• Weather-resistant recycled plastic stands up to outdoor conditions;
• Wipe clean with mild soap; avoid harsh chemicals to protect finish.

Will this base work with my 7–11 ft market umbrella?

Yes — the base is sized and weighted for common 7–11 ft market umbrellas used on patios, porches, and in yards. It can be used as a table-through stand or freestanding base depending on your umbrella configuration.

• Suitable for 7–11 ft market or patio umbrellas;
• Can be placed through an outdoor table or used freestanding;
• Low profile fits beneath many outdoor tables without blocking legroom;
• Black finish matches most umbrella frames and outdoor furniture.
