BFM® spigots and connectors are available in a variety of set diameters in 50mm (2") increments, from 100mm (4") up to 1,650mm (65").
Most of our connectors are available in standard lengths starting at 80mm (3"), then in 50mm (2") increments from 100m (4") up to 6 metres (19ft 8").
(Note: for larger diameters from 700mm (27.5") upwards, certain length restrictions apply).
