All purpose (AP) blocks are a great all around solution. Self-lubricating Acetal polymer sheaves running on polished stainless steel races perform equally well with dynamic loads and high static loads. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

Fiddle blocks are ideal for fine-tune mainsheet tackles, cunninghams, boom vangs, backstays and other control line purchase systems.

Sheave diameter: 40mm, 24mm (1-9/16", 15/16"). See Technical Specs for more information.
