Ronstan, Series 55 Orbit Block™, Clockwise Ratchet Cheek, RF56151

Description

The Ronstan Series 55 Orbit Block™ with clockwise ratchet cheek offers unparalleled flexibility with its automatic and manual engagement modes. In automatic mode, the ratchet mechanism engages under load and disengages when released, allowing for smooth and rapid easing of sheets, ideal for gybing asymmetric spinnakers. In manual mode, you can switch the ratchet on or off as needed, a setup favored by many top sailors. Experience both modes to find your preference.

Ronstan Ratchet Orbit Blocks™ deliver exceptional holding power, featuring a CNC-machined sheave with Generation 2 patented cross-hole geometry. With a holding power of up to 20:1, it nearly doubles the performance of competitors. The sheave's unique design includes 12 gripping faces that resist line movement, minimizing rope wear and distributing load effectively.

Features include up to 20:1 holding power, smooth easing of sheets, high-performance cleating, and both automatic and manual ratchet modes.
