A810 Absestos Extra-Wide No Drill Blackout Shangri-la Blinds

Our extra-wide no-drill system utilizes high-precision internal tension springs and industrial-grade, high-friction silicone end-caps. This engineering generates the substantial, uniform lateral pressure required to support the weight of wide headrails securely without the need for drilling, ensuring your shades remain stable even on larger window spans.

This blackout series utilizes a high-density, multi-layered fabric with an opaque inner core. When the vanes are tilted to the fully closed position, it effectively blocks 95–99% of external light. This provides near-total darkness, making it an ideal choice for bedrooms, nurseries, and home theaters.

No. We use reinforced, high-rigidity extruded aluminum headrails specifically engineered for extra-wide spans. This high-strength material prevents bowing or sagging, ensuring that the shade maintains a perfectly level, high-end aesthetic over its entire lifespan.

To ensure a stable and flush inside-mount installation, we recommend a minimum window frame depth of 7cm (2.76 inches). This provides sufficient clearance and surface area for the tension end-caps to grip effectively, keeping the headrail securely tucked within your window frame.

For extra-wide installations, precision is critical. Measure the interior width of your window frame at three points: the top, middle, and bottom. Always use the narrowest of the three measurements for your order to guarantee a secure tension fit without straining the mechanism. See Our Step-by-Step Measurement Guide.

Yes. Our shades are designed with a 100% cordless, handle-operated mechanism. By completely eliminating dangling lift cords or chains, we remove potential entanglement hazards, making this the safest and most minimalist window treatment option for families.

No. Each headrail features specialized, high-friction, non-marking silicone end-caps. These are engineered to provide a firm, secure grip while distributing pressure evenly, ensuring that your window frames remain completely free of scratches, dents, or adhesive damage.

Yes. The fabric is designed for durability and low maintenance. Routine care simply requires using a vacuum with a soft brush attachment on low suction to remove surface dust. For minor spots, wipe gently with a clean, slightly damp microfiber cloth. Avoid harsh chemicals to preserve the blackout coating.
