The SLB1250, 1250mm dia. Navigation Buoy, has proven its superior performance in many parts of Australia and around the world for long-range river and sea navigation.

The base is moulded in one-piece, strong, coloured, durable polyethylene – filled with closed-cell polyurethane and UV-stabilized for resistance to sunlight.

The strong, lightweight polyethylene buoy top is moulded in standard IALA high visibility colours and shapes to suit a range of installation requirements.

For superior night visibility, the SLB1250 navigation buoy may be fitted with a range of Sealite solar LED marine lanterns up to 5nm+.

Brass inserts provide a secure mounting for top, tower and signs. A 316-grade stainless steel eyebolt passes through the base providing a strong mooring chain attachment point.

In addition, all hardware and fittings are 316-grade stainless steel.
