Una garrucha para persianas caracterizada por el hecho de que su armazón en U, además de presentar el borde inferior-posterior doblado hacia afuera formando canto romo, sostiene cerca de la pared posterior que enlaza a las laterales, a un eje transversal paralelo al de la polea y situado a un nivel más bajo que este, sobre el que gira loco un pequeño manguito o rodillo montado apropiadamente para que la cuerda que pasa por la garganta de la polea, se apoye sobre dicho rodillo al perder la verticalidad inclinándose en el sentido de acercarse a éste.
