This 100% blackout roller blind features a specialized rubber backing that blocks all incoming light to ensure complete privacy and room darkening. Built on a reinforced 25 mm aluminum tube, it mounts easily to the wall, ceiling, or window recess for smooth and reliable operation. Designed to deliver total darkness and reliable privacy, the PG-04 roller blind incorporates high-performance blackout textile. A specialized rubberized backing on the window-facing side reflects incoming daylight and completely stops 100% of external light from penetrating, making it well-suited for bedrooms, media spaces, and rooms requiring strict glare management. The blind is engineered around a sturdy 25 mm diameter reinforced aluminum roller tube. This heavy-duty structural core supports the fabric evenly across its broad 220 cm span, preventing rippling, sagging, or fabric waviness over extended periods of everyday use. Installation is adaptable to diverse interior layouts, allowing direct mounting to the wall, ceiling, or within a window recess using the supplied screws and wall plugs. With a total width of 225.5 cm and a fabric drop of up to 170 cm, it delivers comprehensive coverage across broad window openings. Smooth and flexible operation is supported by a reversible control mechanism that can be installed on either the left or right side according to your room configuration. An integrated self-locking brake system holds the fabric securely at any selected height, preventing unintended slipping or unrolling. Everyday safety and convenience are incorporated into the chain control setup. The mechanism includes a child-safe breakaway connector that separates under undue strain and easily snaps back together, while a dedicated bottom chain weight keeps the cord taut, untangled, and close to the wall.
