Radz Pulley Hook 4-Roller
Strong, reliable, high-quality windsurfing pulley hook from Radz. The 4 brass rollers within the sturdy cast aluminium body give a 8:1 purchase when used with a 3-roller mast extension. This version has the standard diameter rollers and is the most popular type.
Essential for use on windsurfing sails with a tack cringle (the metal ring in lower corner of the sail) to prevent high friction on the downhaul and to make downhauling much easier and smoother. Not required for windsurfing sails with a tack pulley already sewn in.
