Product Information

Ronstan Fiddle block with Becket and Universal head.

Ronstan Series 40 all-purpose (AP) Fiddle block with Becket and Universal head is ideal for smaller yachts.


  • Self-lubricating Acetal polymer sheaves running on polished stainless steel races perform equally well with dynamic loads and high static loads.
  • These blocks are the right choice for sheets, halyards, and control line applications for cruising and racing.
  • They are ideal for durability and long service life.
  • The captive lock universal head can be fixed in either of two planes, or free to swivel as required.
  • The Becket pin is removable so a line can be spliced before fitting and is ingeniously locked into position without the use of a clevis pin, split ring, or tools.
  • Used for mainsheet, halyard, and vang lines.
  • Also for spinnaker control lines on off-the-beach catamarans, one design classes and sports boats up to 8m.
  • Ideal for fine-tuning mainsheet tackles, Cunninghams, backstays, and other control line purchase systems.
