Triton 450 Pen

Wide view of six Triton 450 fish pens on the water with a workboat in the centre

The perfect pen for high energy environments, the Triton 450 system is based on a tried and tested pipe floatation ring of 450mm diameter covering pen sizes from 100 to 180 metres.

Being all engineered plastic, they are extremely low maintenance and very long life.

In higher energy sites Triton 450 provides safety for people and stock.
