CLGR® JIS Ship Wooden Block With Link Double Sheave, also known as JIS Wood Pulley With Link.
Crafted from high quality wood and fitted with a hot-dip galvanized steel link, this wooden block minimizes line chafing while providing a smooth 180° rope redirection.
This JIS Wood Pulley With Link is a critical component for traditional and modern sailing vessels, engineered specifically for lifting sails, adjusting rigging, and mast control.
It is designed to work in conjunction with ropes, providing mechanical advantage and changing the direction of force. This allows crew members to handle heavy loads with less effort.
