Business & Pleasure Co. Clamshell Base patio umbrella base — Antique White, 55 lb, low-profile & weatherproof

The Clamshell Base by Business & Pleasure Co. is a 55 lb antique-white patio umbrella base designed to secure umbrellas up to 11' while resisting outdoor wear and sliding easily across surfaces.

Give your outdoor shade solution a polished, durable foundation with The Clamshell Base. This signature Business & Pleasure Co. design blends a classic clamshell silhouette with practical engineering: heavy-gauge galvanized carbon steel, a weatherproof powder-coat finish, and stainless-steel self-leveling feet for smooth movement. It works with or without a patio table and includes an insert for slimmer poles, making it versatile for most residential umbrellas.

Will this base keep my umbrella steady on windy patios?

The 55 lb weight offers reliable ballast for umbrellas up to 11' in diameter under normal conditions. The wide footprint and solid construction reduce tipping, and the included pole insert ensures a snug fit for smaller-diameter poles.

How does The Clamshell Base hold up to weather and wear?

Can I move the base easily across my patio or deck?

Yes — stainless-steel self-leveling feet let you slide The Clamshell Base smoothly across flat surfaces without scratching. The feet reduce friction when repositioning and are compatible with The Wheel Set for even easier transport over uneven ground.

• Self-leveling stainless-steel feet for easy sliding and surface protection
• Works with The Wheel Set for rolling mobility

Will this base fit under my patio table and match my outdoor decor?
