Harken 57mm Carbo Air Fiddle Block w/Swivel & Becket

The Harken 57mm Carbo Air Fiddle Block with Swivel & Becket is a precision load-management tool designed for vehicle recovery, winch systems, and heavy-duty rigging applications where mechanical advantage and directional control are critical. This compact fiddle block allows operators to redirect load angles while maintaining structural integrity under tension, making it essential for off-road recovery, towing operations, and automotive winch setups.

Built by Harken, a leader in high-performance marine and automotive hardware, this block delivers the reliability mechanics and recovery professionals depend on when equipment failure isn't an option. The 57mm construction delivers lightweight strength without sacrificing load capacity—critical when every pound matters in winch systems or vehicle-mounted rigging. The swivel connection allows the block to rotate freely under load, preventing rope twist and eliminating binding that can reduce efficiency or damage line integrity.

The integrated becket (attachment point) accommodates standard shackles and recovery hardware, while the fiddle-block design enables a 2:1 mechanical advantage when properly rigged, multiplying pulling force while reducing load on primary anchor points. At just 0.3 pounds with compact 3 x 1 x 7-inch dimensions, this block mounts easily to vehicle frames, bumper systems, or fixed recovery points without adding bulk. Recovery specialists, off-road mechanics, and winch operators benefit most from this block's versatility and efficiency.
