Description
Ronstan Series 60 Pivoting Low Lead Ratchet Block – RF62174:
Features:
- Unrivalled 20:1 holding power.

The patented extruded hole design, in conjunction with the groove profile of the sheave, provides a more powerful grip than conventional designs – up to 20:1 holding power. Unrivalled low weight is achieved by the use of a Torlon® ratchet pawl, high grade machined alloy sheave and black Acetal hubs and bearings. On-Off switching knob is fitted to both sides of the swivel blocks (one can be removed if desired). Ratchet blocks can be disassembled for sheave replacement with RF62000.
Materials:
- Mainsheet on powerful dinghies and skiffs.
- Series 60 mainsheet systems on sports boats using RF7 mainsheet swivel units.
- Control line applications on larger yachts.
- Spinnaker sheets on sports boats and small keel boats (lateral lead blocks).
