Harken 16mm Triple Block

The Harken 16mm Triple Block is the smallest block in Harken's rigging portfolio, engineered for precision control on high-tech sailing dinghies and lightweight synthetic line applications. This compact triple block features a patented bearing system with stainless steel balls seated in a captive grooved race, delivering smooth, low-friction performance in demanding marine environments where every gram of weight and every millimeter of space matter.

Specifications reflect precision engineering for small-diameter control lines. The 16mm sheave accommodates line up to 5mm diameter, with a maximum working load of 318 kg (700 lbs) and a breaking load of 544 kg (1,200 lbs)—sufficient for dynamic sailing loads while maintaining the lightweight profile essential to competitive and recreational sailing applications. The block measures 46mm in length and weighs only 41 grams, minimizing total system weight without sacrificing load-handling capability or reliability.

This block serves sailors and rigging specialists who demand proven performance in small-scale tackle systems—spinnaker sheets, traveler lines, boom vangs, and other control applications where minimal friction and compact dimensions are non-negotiable. The stainless steel bearing system resists corrosion from salt spray and extended water exposure, making it suitable for both freshwater and saltwater racing. Harken's 16mm triple block is ideal for those building or maintaining high-efficiency sail systems where material quality and mechanical precision directly influence boat handling and crew efficiency.
