The Antal Solid Rings are realised in a hard black anodised aluminium material with 4 size models from 30 to 50 mm, it's the simplest idea for maximum load and minimum weight.
Compared to the Low Friction Rings, the Solid Rings have a thinner body and a wider hole with the same extreme working loads.
The outer groove is suitable for a hanging line. Minimum friction, highly polished, hard black anodised aluminium body. The solid rings have been specifically designed for reefing and for 3D setting of the genoa sheet.
