Dog Screen Door, Flap Opening 11.2 x 14.4 inches, Dog Door for Screen Door, Large Pet Door for Sliding Door Magnetic Self-Closing, Screen Door with Doggie Door Built in, Lockable, Black

Review: Muy práctico, buena calidad. Fácil de instalar en la maya, no es muy pesado, está hecho de plástico. Y tiene seguros por si quieres dejar afuera a tus mascotas para que no entren. Yo pedí un tamaño mediano porque mis mascotas son talla chicas y talla mediana. Trae todo lo que necesitas para instalarlo.
Review: Cumple perfectamente con la función de ser una puertita para perros y para gatos. Me sirvió mucho para los insectos al antes tener que estar dejando abierto. Tiene imanes para que quede automáticamente fijo hasta que la mascota haga un poquito de fuerza. El instructivo no es claro en cómo debe instalarse, pero es sencillo. Se separa el producto en dos, se coloca una de las piezas de un lado del mosquitero y se encajan los picos de plástico, con una navaja cortas el contorno del mosquitero que queda por dentro, lo pones en el medio de las otras dos piezas de plástico, se coloca donde debe de estar y posteriormente se coloca el otro lado coincidiendo los orificios de la otra pieza. Accidentalmente lo solté varias veces y me quedó un poco chueco. Casi no se nota. Recomiendo mucho que lo hagan con ayuda de otra persona. Mis gatos aún no aprenden a usarlo, espero que eventualmente aprendan. 9/10
