Harken's Airblock range is our highest quality Micro Pulley. It is ideal for small synthetic fiber trim lines on high-tech dinghies. The patented bearing system uses stainless steel balls, allowing for a higher working load than any Micro Pulley.
The vertical pulley mounted on a 16mm Air Block axle will allow you to create a static return at the foot of the mast or to use each side of the axle on each edge.
