Glasdon lifebuoys are ideal buoyancy aids for use around harbours, ports, piers, canals, rivers and any location where there is a drop to the water. The lifebuoy, also commonly referred to as a life saving ring, is manufactured in tough polyethylene, making it extremely durable under the most adverse conditions. Available in two standard sizes, 600mm (24") or 750mm (30"), with varying rope lengths as required.
