Rhino BaseMate Patio Umbrella Base Weights — Square 4‑Piece Fillable to 200 lb with 900D Weather-Resistant Cover

The Rhino BaseMate is a 4-piece, heavy-duty EVA umbrella weight system that secures cantilever, offset, and regular patio umbrellas with up to 200 lb of fillable ballast.

Designed for stability and long-term outdoor use, the Rhino BaseMate combines rugged EVA water-resistant containers with a 900D polyester cover to protect your umbrella on decks, patios, and poolside spaces. Its patent-pending design places the ballast over the cross-base legs rather than between them, improving stability for freestanding and offset umbrella setups. Lightweight and compact when empty, the kit packs down for storage and is easy to fill, transport, and reassemble season after season.

How does Rhino BaseMate improve umbrella stability?

Rhino BaseMate increases base traction and lowers umbrella tipping risk by allowing up to 200 lb of sand, gravel, or stones to be distributed over the base legs. The design concentrates weight where it best counteracts the umbrella canopy’s leverage, especially for cantilever styles.

• Four separate EVA containers create an even weight footprint over cross-base legs.
• Fill capacity up to 200 lb—enough ballast for larger canopies.
• Stackable, low-profile square shape resists uplift and shifting.

Is it easy to set up and take down for seasonal use?

Yes. Rhino BaseMate was built for simple, no-mess operation. A large filling opening and A-grade hook-and-loop closures make adding ballast quick, and the pieces detach and fold flat for winter storage or transport.

• Wide-mouth fill port speeds sand or gravel loading.
• Durable hook-and-loop fasteners keep sections secure yet removable.
• No small parts to lose—each unit assembles in seconds.

Will the materials hold up outdoors and in extreme temperatures?

The BaseMate uses waterproof, high-density EVA for the ballast containers and a 900D polyester outer cover treated with a PU waterproof layer and UV coating. These materials resist cracking, fading, and moisture exposure so the system performs across seasons.

• EVA ballast containers are anti-cracking and weather-resistant.
• 900D polyester cover includes PU waterproof layer and UV protection.
• Suitable for sun, rain, and temperature variation without losing integrity.

Which umbrella bases and setups are compatible?

Rhino BaseMate works with most base types—x-shaped cross-bases, square, round, and cantilever/offset systems. The square, low-profile layout fits over cross legs and around center posts for broad compatibility.

• Fits over cross-base legs—ideal for cantilever umbrellas.
• Compatible with round and square umbrella bases as an added weight layer.
• Universal sizing (31.5 x 5.5 inches per section) accommodates common base geometries.

Who this product is for: Rhino BaseMate is aimed at homeowners, poolside and patio designers, and hospitality operators who want a durable, easy-to-store solution for securing umbrellas—especially cantilever and large canopy styles. Choose this if you need a high-capacity, weather-ready ballast system that’s simple to fill, remove, and protect from the elements while delivering reliable resistance to tipping and uplift.
