Ronstan RF51530 Series 50 All Purpose Block Fiddle with Becket and Cam Cleat

All-purpose fiddle block with becket, adjustable cam cleat and universal head. Suitable for mainsheet and halyard applications, vang and spinnaker control lines on boats to 10m (33'). 

It is ideal for fine-tuning mainsheet tackles, cunninghams, backstays and other control line purchase systems.

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 long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

Captive Lock™ universal head can be fixed in either of two planes or free to swivel as required.

Quick-adjusting cleat arms require no tools to adjust and are fixed securely in position. The becket pin is removable, so a line can be spliced prior to fitting.
