A111 Blackout Cordless Square Cassette Roller Shades

Yes. Our blackout fabric features a high-density, multi-layer construction designed to block 99% or more of visible light. When installed as an inside mount, it minimizes light leakage around the edges, making it ideal for bedrooms, home theaters, or nurseries where complete darkness is desired.

The Square Cassette provides a modern, minimalist architectural finish that conceals the roll mechanism and mounting brackets. It also functions as a durable dust-cover, protecting the blackout fabric from dust and pet hair, which ensures the shade operates smoothly and looks pristine for years.

Yes. Our premium cordless system replaces traditional lift cords and chains with a high-precision, internal constant-tension spring motor. By eliminating all dangling components, it removes the primary entanglement hazard, making it the safest window treatment choice for homes with young children or pets.

To ensure the square cassette fits flush within your window frame, we recommend a minimum installation depth of 10cm (4 inches). This provides sufficient clearance for the mounting brackets and the cassette profile to be secured properly.

For inside mounts, measure the precise width at three points (top, middle, and bottom) and use the narrowest measurement. For height, measure from the top of the frame to the sill. See Our Step-by-Step Measurement Guide.

Yes. Outside mounting is an excellent option if you have shallow window frames or want to maximize window coverage. We recommend adding 5–10cm (2–4 inches) to your width and height measurements to ensure the cassette box fully overlaps the window opening for optimal light blocking.

Routine maintenance is simple. Use a vacuum with a soft brush attachment on a low-suction setting to gently remove surface dust. For spot cleaning, dab the area with a slightly damp, clean microfiber cloth; avoid harsh chemical cleaners or heavy scrubbing, which could compromise the blackout backing.

Yes. Every order ships with a complete, high-durability installation kit including mounting brackets, wall anchors, and screws, designed for quick and professional-grade installation for both inside and outside mount configurations.
