The rings are manufactured from a high-grade, corrosion-resistant alloy. They are “drum polished” to ensure smoothness as well as maximum static friction, guaranteeing the highest knot strength. Finally they are anodised, resulting in a grey black sheen that reflects very little light. The rings increase the braking strain of connections between two lines of up to 100 !Also enclosed are mounting instructions, knot sketches and breaking strain table.
