A 6.5Kg recycled PVC foot cover. Anti-slip studs on base for grip to surface and stacking together. The Surefoot Bloc can be put over the Surefoot feet of a Frontier and Titan barriers to add extra weight more effectively than alternative methods such as using sandbags. They can also be used as a weighted anchor for the Frontier using one of its carry handles to accept the telescopic stability poles and join it to the barrier.
