Ronstan’s new 40mm block range, featuring 23 configurations,are lightweight and strong. Toughened glass fibre-reinforced nylon cheeks combine with a two-stage bearing system to ensure the best performance.

Maximum working loads for the new Series 40 Orbit Blocks™ range from 400kg to 1000kg (HHL versions).

These increased working loads create opportunities for applications on larger boats. The new blocks feature a wider sheave profile able to accommodate lines up to 10mm. Blocks in this range are suitable for mainsheet systems and spinnaker sheets on dinghies, off-the-beach catamarans, and sportsboats to 8m (26ft); halyard, vang and backstay applications on boats to 9m (30ft) and control line applications on larger yachts. Multiple sheave configurations allow users to create up to a 12:1 purchase mainsheet system for performance multihulls.
