Two-pack — 57mm 1.5x & 2x Grip Ratchet Blocks

Harken Two-pack — 57mm 1.5x & 2x Grip Ratchet Blocks

The Harken Power3 ratchet block two-pack is engineered for sailors who race small one-design boats and need versatile holding-power options across a wide range of conditions. By including both a 1.5x and a 2x Grip Ratchet Block in a single package, Harken gives racers the flexibility to configure their rigging for maximum performance in any breeze.

The 1.5x grip block is optimized for use in breeze-on and puff conditions, delivering 15:1 holding power to keep sheets manageable without overloading the sailor. The 2x grip block steps up to 20:1 holding power, making it the go-to choice in big, steady breeze where greater load control is essential. Together, these two blocks allow sailors to fine-tune their setup in tandem with their purchase system, achieving the ideal level of power, responsiveness, and grip for any wind scenario.

Both blocks feature an on/off switch that can be operated from either side of the block, providing convenience and adaptability during racing. The 57mm sheave diameter and compatibility with lines up to 3/8 in (10 mm) make these blocks well-suited for a wide variety of small boat applications. The robust construction supports a maximum working load of 500 lb (227 kg) and a breaking load of 2,000 lb (907 kg), ensuring reliability even under demanding race conditions.
