Harken 2656 40mm Carbo Air Fiddle Block with Swivel and Becket

The Harken 2656 is a high-performance 40mm fiddle block featuring Carbo AirBlock® construction for an exceptional strength-to-weight ratio. This versatile block with becket is ideal for 3:1 and 4:1 tackle systems on dinghy vangs, mainsheets, and high-load control lines on small keelboats.

Carbo AirBlock Technology:

Harken's award-winning Carbo AirBlocks represent a breakthrough in block design, earning both the Dame Award and Sail Magazine's Freeman-Pittman Award for innovation. These blocks are consistently 30% lighter and 60% stronger than equivalent conventional blocks, thanks to UV-stabilized, fiber-reinforced composite sideplates designed specifically for the small-diameter lines favored by racing sailors.

Key Specifications:

• Sheave diameter: 1 9/16" (40mm)
• Maximum line diameter: 3/8" (10mm)
• Maximum working load: 485 lbs (220 kg)
