SPIGOT AND SOCKET SIZES
Extension spindles are normally supplied with a cast steel male spigot at one end of the spindle and a cast steel female socket at the other end of the spindle. The spigots and sockets are pinned to the extension shaft using an 8mm hardened and ground steel dowel, (as details B & C). The spigot or socket is then 6mm fillet-welded to the extension spindle (round bar or tube).

The lift size as shown on sketch A will be taken from top of valve cap to top of spigot unless otherwise specified by the customer on the official order. Standard extension spindles finished ‘Hammerite’ blue or galvanised as required.
