A221 Achat Extra-Wide Kein Bohr Blackout Zebra Shades

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 or permanent hardware, ensuring your shades remain stable even on larger windows.

The Agate series utilizes a high-density, multi-layered blackout fabric. When the opaque vanes are fully overlapped, it effectively blocks 95–99% of external light. This makes it an ideal choice for bedrooms, nurseries, and media rooms where minimizing light intrusion is a priority for sleep or entertainment.

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 and high-end aesthetic over its entire lifespan.

To ensure a stable and flush inside-mount installation, we recommend a minimum window frame depth of 8cm (3.15 inches). This provides sufficient clearance and surface area for the tension end-caps to grip effectively and keeps the headrail neatly 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. Routine maintenance is simple: use 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 fabric's blackout coating and unique pattern.
