Los bloques de guía verticales Thern ofrecen una manera segura y fácil de cambiar la dirección de un cable de cabrestante y se usan comúnmente en aplicaciones donde el cabrestante está colocado de manera incómoda o una línea necesita pasar alrededor/sobre/debajo de un obstáculo.
Ofreciendo capacidades de cable de hasta 1/2", el bloque de plomo Thern cumple incluso con aplicaciones de elevación y tracción de alta resistencia.
Manténgase seguro cuando no esté bajo carga: con muchos otros bloques de polea, la cuerda puede deslizarse fácilmente y provocar un accidente; con el bloque de guía Thern, la cuerda se mantiene en la polea mediante 'guardacables' en la parte superior y los lados de la polea.
