Ronstan, Series 40 Ball Bearing Orbit Block™, Single, Swivel, RF48100

Description

The new Series 40 ball bearing Orbit Blocks™ provide the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fibre reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks, ensuring optimal performance and reliability.

The RF48100 Single Block features a 40mm (1 9/16") sheave and incorporates a 2-stage bearing system. Ball bearings minimize friction, while a secondary full-contact bearing maintains low friction across the full working load range. This product does not have a locking headpost, which is only available in the multiple sheave variants. The RF48100 is free swivel rotation only and can accommodate a maximum rope diameter of 10mm (3/8").

Applications include mainsheet systems and spinnaker sheets on dinghies, off-the-beach catamarans, and sportsboats up to 8m (26ft). It is also suitable for halyard, vang, and backstay applications on boats up to 8m (26ft), as well as control line applications on larger yachts.
