A127 Premium Blackout Cordless Square Cassette Roller Shades

Our Premium Blackout fabric features a high-density, multi-layer construction with a specialized opaque backing. When fully closed, it effectively blocks 99% of visible external light and harmful UV rays, making it the ideal solution for bedrooms, nurseries, and home theaters where near-total darkness is required.

The Square Cassette provides a clean, contemporary aesthetic that completely conceals the roll mechanism and mounting hardware. Beyond its minimalist look, the cassette box protects the fabric from dust, debris, and pet hair, ensuring your shade remains pristine and operates smoothly for years.

Yes. Our premium cordless system uses a high-precision, constant-tension spring motor that allows for effortless, smooth adjustment. By eliminating all dangling lift cords or chains, it removes common entanglement hazards, making it the safest and most minimalist choice for families with children or pets.

To ensure a flush, secure inside-mount installation of the square cassette, we recommend a minimum window frame depth of 10cm (4 inches). This provides adequate clearance for the brackets and the cassette box to be mounted securely within your window frame.

For inside mounts, measure the exact width of the window frame at the top, middle, and bottom; use the narrowest measurement for your order. For height, measure from the top of the frame to the sill. See Our Step-by-Step Measurement Guide.

Yes. These shades are versatile and suitable for outside mount (on the wall or frame surface). We recommend adding at least 5–10cm (2–4 inches) to your width and height measurements to ensure maximum light coverage and minimize light leakage around the edges.

Routine maintenance is simple. Gently vacuum the fabric with a soft brush attachment on a low-suction setting to remove dust. For spot cleaning, use a slightly damp microfiber cloth to dab the affected area; avoid harsh chemical cleaners or vigorous scrubbing, which could compromise the blackout coating.

Yes. Every shade ships with a complete installation kit, including high-durability mounting brackets, wall anchors, and screws suitable for both inside and outside mount configurations, ensuring a professional, stable installation.
