The Thern Vertical Lead Blocks are used to change the direction of the rope, so a winch can be mounted in a convenient location. The blocks can all be used to guide a rope around obstacles, reducing hazards and extending rope life. The top and side cable keepers provide additional security to prevent the rope from jumping out of the sheave in slackline conditions. The large diameter sheaves help to reduce wear and tear to extend the rope life. The steel sheaves provide an extended life for both the sheave and the life of the line. The sealed needle roller bearing provides smooth rotation with load-bearing strength for larger loads and is easily accessible for maintenance.
