Designed by us and machined from Austenitic 304 non-magnetic stainless steel. Chosen to be the optimum combination of durability, precision machinability and high resistance to the environment, we are hugely pleased with the performance of these spikes/domes.

They are supplied with a suitable spanner for tightening the locknut.

At present the only way to get a set of these is to buy a pair of Borg or WM-4 but we are considering if we will make these available via our website later this year.
