Detailed Description
Up to 100 kg of ballast for your cantilever umbrella, in four plates you fill yourself. A cantilever needs serious weight on its cross-stand: this kit adds it, then comes apart when the season ends.
For cantilever umbrellas with a cross-stand only. For market umbrellas, see the Socle or Roche bases.
Some products may be shipped directly from our partner vidaXL's warehouses.

Installation and Maintenance
The Holdfast Base Weight Kit can be installed without tools in under 15 minutes. Position your cantilever umbrella in its intended location with the cross base in place. Arrange the four plates around the base and fit them over the horizontal crossbars. Fill each plate through the upper opening with dry river sand, allowing approximately 17 litres or 25 kg per plate. Securely replace the caps once filled.
Minimal routine maintenance is required. Wipe the plates with a soft, damp cloth and periodically check the caps, plate bodies and contact points for damage or loosening.
During extended periods of non-use, the plates may be emptied and stored in a dry, sheltered location where practical.
Frequently Asked Questions
Is the sand included?
No. The kit includes four empty sand-fill plates and their caps. The sand must be purchased separately before installation.
How much sand is required?
Each plate holds approximately 17 litres or 25 kg of dry sand. Allow around 68 to 70 litres of sand in total to reach the kit’s maximum combined weight of approximately 100 kg.
Is this kit compatible with my cantilever umbrella?
The kit is designed for cantilever umbrellas fitted with a compatible cross base. Compare the dimensions and shape of your umbrella’s cross base with the compatibility information shown on this product page before ordering.
Can the plates be filled with water?
This model is intended to be filled with dry sand. Sand provides more weight than water for the same volume and is therefore the recommended filling material. Follow the filling instructions supplied with the kit.
Does the 100 kg weight make the umbrella windproof?
No umbrella or ballast system should be considered windproof. When fully filled, the four plates provide up to approximately 100 kg of additional ballast, but the canopy must still be closed during strong or gusty winds and whenever the umbrella is left unattended.

THE ART OF STABILITY
Up to 100 kg of Added Support
Four anthracite polypropylene sand-fill plates, providing up to 100 kg of total ballast when filled.
STABILITY FIRST
The Difference Between Shade and a Safety Hazard
An umbrella is only as stable as its base. Ours are engineered to anchor securely against wind gusts, so your umbrella stays upright and everyone underneath stays safe.
BUILT FOR CANTILEVERS
The Weight a Cantilever Umbrella Actually Needs
A 4 piece modular system that fills with sand up to 100kg, matched to your cantilever's cross base for the stability a side-post design really needs.

Frequently Asked Questions
What is included with the Holdfast Base Weight Kit?
The kit includes four hollow polypropylene ballast plates with removable filling caps. Sand, the cantilever umbrella and the umbrella’s cross base are not included unless otherwise stated on the product page.
How is the base weight kit installed?
Place the cantilever umbrella in its intended position with its cross base resting on a flat, stable surface. Arrange the four plates around the base and fit them over the horizontal crossbars. Fill each plate through the upper opening with dry sand, then securely replace the caps.
What type of sand should I use?
Use clean, dry sand that can pass easily through the filling openings. Dry river sand or general-purpose building sand may be suitable. Avoid wet or heavily compacted sand, as it can be more difficult to pour into or remove from the plates.
Do all four plates need to be completely filled?
Filling all four plates evenly provides the kit’s maximum combined ballast of approximately 100 kg. Partially filled or unevenly filled plates will provide less support. Always follow the base-weight recommendations supplied with your umbrella.
Can this kit be used with a market umbrella?
The kit is primarily designed for cantilever umbrellas with a compatible cross base. Most market umbrellas use a centre-pole base and therefore require a different style of umbrella stand. Check the base design and compatibility measurements before ordering.
