I'm pretty sure this suits an EQ6 but could also be used for the HEQ5? The spigot internal diameter is approximately 67mm. The tube column is 100mm in diameter, overall height is approximately 970mm and both flanges are 215mm in diameter. Just needs 3 x 1/2" Whit. nuts for the underside of the top flange. $150 pick up only from Bleackheath, NSW.
