Harken FLY Block 18 mm, high performance sailing block, lightest and most robust design

Harken FLY blocks are the lightest blocks Harken has ever built. They are used wherever maximum performance and minimum weight are required. The absence of metal shackles or rivets and the use of fiber-reinforced composite make the 18 mm FLY block extremely light yet robust. The loop stop through the block's center directs the forces directly to the sheave. This relieves the strain on the cheeks and increases the block's load-bearing capacity. It can be tied, lashed, or spliced ​​to almost anything. Delrin® ball bearings in a curved bearing cup ensure even load distribution, for maximum load-bearing capacity with minimal friction. A Spectra line with a polyester cover is included.
