The Apex 1m VisiBall extension lengthens the standard 2m indicator tube to a maximum assembled height of 3m. It is an accessory for the VisiBall water level indicator and requires two 150mm bottom floats in the extended setup.
The extension includes a twin-float connector and female socket. Add one 150mm Apex ball float in black or orange, sold separately.
Keep the completed tube vertical through the adjustable roof joint. The manufacturer wind limit reduces from 120km/h for the standard 2m arrangement to 80km/h at 3m.
