The Harken 346 is a high-strength, lightweight, triple-sheave pulley featuring:

• 29 mm Delrin® sheaves on precision stainless steel ball bearings

• Full 360° stainless swivel head to prevent line twist

• Integral 471 Micro Carbo cam cleat, reversible for up/down cleating

• Lightweight Carbon® side cheeks for stiffness and durability

• Supports up to 6 mm (1/4″) line diameter

• Working load: 340 kg (750 lb); breaking load: 680 kg (1,500 lb) 

• Weighs just 130 g (4.6 oz) 

The open Carbo Air design trims unnecessary weight while boosting strength—making the 346 about 30% lighter with a 60% stronger working load than classic blocks . Its triple-sheave layout is ideal for 4:1 to 6:1 purchase systems, commonly used in vang, outhaul, traveler, and halyard control setups.

Perfect for performance dinghies, beach cats, skiffs, and small racing yachts, this block combines exceptional mechanical advantage, compact form, and cutting-edge materials.
