The base is moulded in one-piece, strong, coloured, durable polyethylene – filled with closed-cell polyurethane and UV-stabilised 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 SL-B1250 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.
