Ronstan Series 70 blocks are ultra lightweight, compact, and have a low profile which allows for a 0° or 90° alignment. Blocks feature a low friction 2-stage orbital ball bearing system, simple and secure Dyneema Link head attachment and provide the highest working load in their class.

Designed for a variety of uses and applications in mainsheet systems and spinnaker sheets on dinghies, sportsboats and small keelboats up to 11m (36ft), Halyard, Vang and Backstay application on boats up to 9m (30ft), as well as control line applications on larger yachts.

Constructed from high compression strength carbon black Acetal ball bearings, a UV stabilized multi-strand impregnated SK75 Dyneema rope link, glass fibre reinforced nylon frames and cheeks, and carbon fibre reinforced PTFE impregnated nylon stage 2 bearing.
