Spherical Buoys

Our range of spherical buoys consists of a large variety of sizes and can be delivered for several depths. The buoys consist of a unit, and are adapted for use where the need for buoyancy is limited. The sizes up to and including Ø 450 have a 50mm hole through the buoy for a rope or wire. Padeyes can be delivered as optional equipment. The holes are also excellent for manual handling.

The Ø 800 and Ø 1000 sizes have a hole of Ø 110mm, and are normally delivered with a padeye.

The standard colour is signal yellow. As an alternative, the buoys can be supplied in an orange colour. The buoyancy values are stated for salt water with a density of 1.025 kg/dm3. The weight values are for air.
