BACKYARD EXPRESSIONS PATIO · HOME · GARDEN Offset Umbrella Weight Set 4‑Piece — Fillable Resin Plates, Up to 160 lb Stability

A four-piece fillable weight set from Backyard Expressions that secures most cantilever and offset patio umbrellas by adding up to 160 lbs of ballast when filled with sand or water.

Protect your freestanding offset umbrella from tipping and wobble without heavy lifting or permanent installation. These interlocking resin plates fasten around a standard cantilever cross base, letting you choose water for lighter transportability or sand for maximum stability. UV-resistant construction and integrated handles simplify seasonal setup, teardown, and storage while maintaining a low-profile look on decks, patios, and pool areas.

How much stability will this weight set provide?

Each of the four plates is engineered to accept either water or sand. When filled with sand, the full set reaches about 160 lbs of ballast—enough for most residential offset umbrellas in typical windy conditions. Filling with water yields a lighter, transport-friendly option around 52 liters total.

• Sand capacity: roughly 40 lbs per plate (approx. 160 lbs total)
• Water capacity: 13 liters per plate (52 liters total)
• Interlocking design ensures combined weight sits securely around cross base

Will these plates fit my cantilever umbrella base?

The set is made to clamp around most standard cantilever and offset cross bases, creating a stable footprint without modifying the umbrella. The plates align and lock together around the support frame, so compatibility depends mainly on standard cross-base dimensions rather than umbrella brand. Measure your base diameter against typical cross bases if you have a nonstandard design.

• Designed for most standard offset/cantilever cross bases
• Plates lock together to encircle the base for unified ballast
• Not a replacement for a cross base—fits around existing support

How easy is setup, filling, and seasonal storage?

Setup requires no tools: place the plates around the umbrella cross base and snap them together. Large screw caps and wide fill ports speed filling and draining, while built-in molded handles make lifting and carrying manageable even when empty. For off-season storage the plates stack flat to conserve shed or garage space.

• Wide fill ports with screw caps for fast filling and draining
• Molded carry handles for easy transport when empty
• Stackable design for compact winter storage

What are the materials and outdoor durability features?

The plates are constructed from heavy-duty, weather-resistant resin that resists cracking, fading, and UV damage for reliable seasonal use. The plastic shell keeps the ballast contained while maintaining a low-profile aesthetic that blends with most outdoor furniture. Routine rinsing and winter storage will extend service life.

• Durable, UV-resistant resin construction
• Non-corrosive design suitable for outdoor exposure
• Low-profile finish to complement patio decor

Who is this for? Homeowners and renters with cantilever or offset patio umbrellas who want a nonpermanent stabilizing solution will benefit most. It’s ideal for those who need the option of lighter water ballast for portability or heavier sand ballast for maximum stability, plus anyone looking to avoid complicated installation or extra tools.
