Ronstan Series 40 All Purpose Block - Fiddle - Becket - Cleat

Route sheets, halyards or control lines through the Ronstan Series 40 All Purpose fiddle block with becket and cleat. For cruising and racing setups, its self-lubricating sheaves handle both moving loads and high static loads, while adjustable fittings let you set the block and cleat positions.

• The Captive Lock™ head can swivel freely or lock in either of two planes to suit the line arrangement.
• A cleat arm adjusts without tools and secures at the chosen angle.
• The removable, snap-fit becket pin lets you splice the line before installation.
