Aluminium Low Friction Rings - Marine Rigging Services Discover the Marine Rigging Services low friction rings, the ideal, lightweight, and ultra-durable alternative to traditional blocks. Designed with no moving parts, these rings offer exceptional load capacity with minimal weight and bulk. Manufactured from marine-grade aluminium, our rings feature a hard anodised finish in a sleek black colour. This technical coating not only guarantees maximum resistance to corrosion and wear but crucially creates an ultra-smooth surface that drastically reduces rope friction. Key Features: • Unfailing Reliability: The absence of sheaves or bearings eliminates any risk of mechanical failure, even under extreme static loads. • Premium Finish: Hard anodised black aluminium ensures a perfect glide and increased durability against harsh marine elements. • Weight Saving: An ultra-lightweight solution to optimise your yacht's rigging without compromising on safety. Versatile On-Board Applications: These friction rings are the perfect solution for control line systems that need to handle high loads with occasional adjustments or minimal travel: • Backstay and kicking strap (vang) cascades • Barber-haulers and in-haulers • Lazy Jack systems • Clew adjustments (headsails and mainsail) • Deflectors and various fairleads Rigging Advice: To fully exploit the potential of these low friction rings, we recommend securing them using a strop, loop, or lashing.
