Small Boat Pulleys - Fly Blocks Range - 18 Mm - Harken

18mm Fly Block Pulley - Harken: Performance and Reliability

The 18mm Fly Block Pulley from Harken is designed to provide optimal performance in demanding conditions.

These lightweight and compact pulleys are equipped with stainless steel ball bearings with an integrated central path and rivet, also made of stainless steel, and feature cheeks made of composite material reinforced with fibres. 

The Harken Fly Blocks with through-deck attachment stand out for their high strength and lightweight design.

Specifically designed for technical ropes, these high-performance pulleys display an exceptional working load for their compact size.

The Fly Blocks are ideal for sports yachts and foiling dinghies, as well as for cascading backstays and runners on Grand Prix racing yachts.

Use the 18 mm "wasp size" model for applications requiring the pulley to be attached as close to the deck as possible.

These pulleys come with a polyester-covered Spectra® line.
