Harken 75mm Carbo Air Block w/Swivel - 2660
The Harken 75mm Carbo Air Block with Swivel – 2660 is engineered for sailors who demand high load capacity, low friction, and dependable durability in active trimming systems. Designed for mid-to-large size boats and high-load control lines, this block delivers smooth, efficient performance whether you’re racing or cruising.
Advanced Carbo Air Construction
Harken’s Carbo Air® series is known for combining lightweight composite sideplates with high-strength reinforcing fibers to maximize strength without unnecessary weight. The result is a block that maintains structural integrity under heavy loads while reducing overall rig weight — a key advantage for performance sailing.
Precision Ball Bearing System
The 75mm sheave runs on high-grade Delrin® ball bearings for ultra-low friction and quick acceleration under load. This allows sheets and control lines to run freely, making trimming easier and more responsive — especially important in gusty conditions or during rapid sail adjustments.
360° Swivel Head
The integrated swivel head rotates smoothly to keep the block aligned with the load angle. This reduces line twist, minimizes wear, and ensures consistent performance from any mounting position. The swivel design also allows flexible installation in a variety of rigging setups.
