Inflatable Marker Buoys
Norfloat's NB and A seriesNorfloat's NB and A series of inflatable buoys are available in six standard colours and 13 sizes,. They are widely used as fenders for yachts and work boats throughout the world. The A series has been specifically developed for the fishing industry. The main feature of the buoy is its heavy duty rope eye which is designed not to chafe ropes, and is of a size to suit shackles without modification. The Norfloat valve is simple and effective and allows easy inflation and deflation. The valve is sealed with a plastic screw, which has a very coarse thread that is impossible to cross thread or over- tighten. |
