Harken 29mm Carbo T2 Block

The Harken 29mm Carbo T2 Block is a high-strength composite pulley system designed for load-bearing applications where minimal weight and compact size are critical operational requirements. Unlike traditional metal blocks with shackles and rivets, the T2 composite construction eliminates fastener corrosion and reduces overall assembly weight—a decisive advantage in marine, rigging, and tactical recovery scenarios where every ounce counts and saltwater exposure demands corrosion-resistant equipment.

This 29mm block excels in traveler controls, mainsheets, vangs, cascades, and bridle systems. The composite T2 design tolerates field-rigging methods—it can be tied, spliced, or lashed directly to lines, sails, or load-bearing points without modification. The included Spectra line provides immediate deployment capability. At 0.2 lbs and measuring just 1 x 1 x 2 inches, the block integrates seamlessly into confined spaces and integrated rig configurations where traditional metal blocks create weight penalties and bulk concerns. The material composition resists UV degradation and maintains mechanical integrity in harsh environmental conditions typical of offshore, maritime, and expeditionary operations.

Operators and riggers in maritime recovery, emergency management, sailing operations, and tactical extraction rely on the T2 block for systems requiring lightweight, corrosion-free performance without field modification. The no-metal-fastener design eliminates hidden corrosion points that compromise integrity under sustained load. This block serves professionals managing complex multi-line systems where mechanical reliability, minimal weight, and saltwater durability determine mission success.

The Harken 29mm Carbo T2 Block represents the evolution of composite rigging technology—strength without fastener failure, weight savings without sacrificing load capacity, and field versatility without modification requirements. For serious operators and maritime professionals, composite blocks have become the standard for high-reliability systems.
