33 in x 39 in Blackout Cellular Shades - No Drill Cordless Install

Our review of these cordless honeycomb shades finds them ideal for renters and light-sensitive sleepers who want a fast, damage-free blackout solution. The biggest reason to buy is the combination of a true blackout fabric with a no-drill, no-tools installation system that manages to block light and reduce heat without permanent hardware. Installation takes under a minute, the cordless spring glide operates quietly, and the insulation noticeably cuts light and muffles outside noise, making these shades a practical choice for bedrooms, nurseries, and home theaters.

Key Features

• No-drill installation: The damage-free system installs in about 30 seconds with no screws or tools, so it is perfect for renters or anyone avoiding wall damage.
• Cordless safety: The spring-operated cordless mechanism provides a quiet, pet-friendly operation and smooth, balanced raising and lowering.
• Blackout and insulation: Honeycomb cells trap air to block sunlight, reduce heat transfer and dampen street noise for better sleep and energy savings.
• Custom sizing: Widths are cut 3 mm smaller by default for a precise fit, and custom dimensions are available after confirming your measurements.
• Durable construction: Rust-proof aluminum frame and fade-resistant fabric are lab-tested for 10,000+ lifts and extreme temperature and humidity.

Who It's For

The shades are best for renters, apartment dwellers, and families who need a quick, non-permanent blackout solution; the easy install and cordless design make them especially suited for nurseries and bedrooms. People who want to reduce heat transfer and block UV to protect furniture will also appreciate the honeycomb insulation.

Those who need motorized operation, very large specialty windows, or full room-darkening with multiple layers may want to consider alternatives; likewise, if precise professional mounting or drill-in hardware is required for structural reasons, a traditional installation may be preferable.
