Bird Net Support Wheels

Our heavy duty bird net support offers several advantages over conventional tripod bird net supports.


  • Their larger size helps to increase the surface area supporting the top net thus reducing any point loading.
  • Main flotation ring made from Ø180mm PE pipe.
  • Minimal movement makes them ideal for large diameter pens.
  • Utilises electrofusion process and control.
  • Modular design with the option to increase circumference.

Sinker Tubes

We offer a range of sinker tube options for both 2 and 3 ring pens utilising thick walled, durable polyethylene pipe with options for either chain or wire cores. More information available upon request.

Sinker tubes are a heavy duty thick walled butt fused PE weighted ring suspended sub-surface below the base of the main containment net and can be used for a variety of reasons including:


  • Maximises the main containment net volume in higher current/energy environments which optimises stock holding capacity.
  • Enhances the structure and integrity of the net ensuring convenient use of automated net cleaning technology.
  • Allows better oxygen flow through nets.
  • Can be used with anti-predator netting.
  • Allows for use of smaller mesh nets enabling the use of cleaner fish.
  • The Sinker Tubes internal dead weight is either large diameter wire rope or heavy duty chain internally linked and weight per metre tailored to meet specific site conditions.
  • Equidistant suspension points fitted to the sinker tube include a 3Ton webbing sling choked around the pipe connection to the suspension line with a welded PE stopper either side to hold in position.
  • Flexible suspension lines are available in either rope or chain.
