Fence Ballast Block, Hi-Vis Yellow, 50kg

The 50kg Hi-Vis Fence Ballast Block gives a temporary fence line serious resistance to wind. It sits on a standard thermoplastic foot, close to the panel, alongside the short fence stabiliser, and further blocks stack on top when more ballast is needed.

Tested wind resistance

In our tested set-up (2.0m x 3.5m anti-climb panel, standard plastic foot, angled stabiliser and anti-lift bracket on every panel at 3500mm centres) the fence resisted these maximum wind speeds:

• No added ballast: 24mph
• 1 block (50kg): 52mph
• 2 blocks (100kg): 66mph
• 3 blocks (150kg): 77mph
• 4 blocks (200kg): 88mph

These figures carry no safety factor. Our wind load calculator applies a safety factor, checks the forecast for your site and builds the parts list for you.

Safe handling

We recommend that blocks are handled and installed by at least two people, or with the Brace Blok Lifting Tool. Check the installation regularly, especially after high winds.
