Ronstan, Series 50 All Purpose Block, Fiddle with Becket, RF51510

Description

The Series 50 All Purpose (AP) blocks are versatile solutions for various sailing needs. Featuring self-lubricating Acetal polymer sheaves on polished stainless steel races, they perform well under both dynamic and high static loads. These blocks are ideal for sheets, halyards, and control line applications in both cruising and racing scenarios, offering durability and long service life.

The Captive Lock™ universal head can be fixed in two planes or allowed to swivel freely as needed. The becket pin is removable, allowing for line splicing before fitting, and it locks ingeniously without the need for a clevis pin, split ring, or tools.

Features include exceptionally high working loads, low maintenance, and long service life. The self-lubricating Acetal polymer sheave ensures low friction and extreme durability. The slotted pin shackle prevents fouled lines, and the snap-fit removable becket pin adds convenience.

Applications include mainsheet and halyard uses, vang and spinnaker control lines on boats up to 10m (33ft). It's ideal for fine-tune mainsheet tackles, cunninghams, backstays, and other control line purchase systems.
