The Harken 2141 is a 57mm Carbo Triple Ratchet Block with Becket and Cam, engineered for high-load sailing applications where smooth, efficient line handling is critical. Built with Harken's proven Carbo construction, this block combines a lightweight composite shell with a stainless steel axle and precision-engineered sheaves to minimize friction and maximize performance under load.
The integrated ratchet mechanism engages automatically under load, dramatically reducing hand fatigue during extended sailing by holding the line with minimal effort. The triple-sheave configuration provides significant mechanical advantage, making it ideal for mainsheets, vangs, and other high-tension control systems on performance sailboats. The becket allows the block to be used as the base of a purchase system, while the cam cleat enables quick and secure line locking without additional hardware.
Key Features:
- 57mm Carbo sheave — lightweight, high-strength composite construction reduces weight without sacrificing durability
- Triple-sheave design — delivers mechanical advantage for high-load control lines
- Auto-engaging ratchet — locks under load to reduce hand fatigue and maintain control
- Integrated becket — enables use as the standing end of a multi-part purchase system
- Cam cleat — provides fast, secure line locking built directly into the block assembly
- Stainless steel components — corrosion-resistant hardware for long-term marine use
- Snap shackle compatible — fits standard Harken attachment hardware
The Harken 2141 is a versatile, high-performance block suitable for mainsheet systems, control lines, and purchase systems on racing and cruising sailboats. Its combination of ratchet, triple purchase, becket, and cam cleat in a single unit reduces clutter on deck while delivering maximum functionality.
