Gianna 18 Inch Umbrella Base - 2 Manual Knobs, 30 LBS Resin Base, 2 Adapters, Weather-Resistant, Bronze Powder-Coated Construction for Outdoor Umbrellas

This 16.5"/18" umbrella base offers reliable stability for outdoor market or patio umbrellas, featuring a durable bronze powder-coated steel frame and a weather-resistant resin shell available in 22 lb or 30 lb weights. Equipped with two manual tightening knobs and two adapters (fits 1.5" and 1.9" pole diameters), it ensures a secure, wobble-free hold. Ideal for patios, decks, or poolside use—combining strength, classic style, and all-season durability.

• 2 Knobs for Superior Hold: Features 2 manual knobs (competitors usually have 1) to clamp the umbrella pole tightly. Creates a secure fit that prevents slipping or wobbling in wind.
• 22/30 LBS Weight for Stability: Heavy enough to anchor umbrellas without being too heavy to move. Easy to reposition around your patio, but sturdy enough to resist tipping.
• Weather-Resistant Construction: Resin + lime powder build with a protective coating—waterproof, UV-resistant, and rust-proof (1 year). Handles rain, sun, and humidity without damage.
• 2 Universal Adapters: Detachable adapters fit umbrella poles ≤5cm in diameter. Compatible with most outdoor umbrellas, so you don’t need a separate base for different umbrellas.
• 5-Minute Assembly: No special tools needed—use included hardware to attach adapters and secure knobs. Even if you’re not handy, setup is quick and frustration-free.
