Calyx Interiors Vertical Blinds For Sliding Doors

These vinyl vertical blinds are designed for wide openings such as sliding glass doors, patio doors, and large windows. The 78″ headrail fits inside or outside mount configurations, measuring 78″ wide by 84″ tall. The vanes offer smooth side-to-side operation, full privacy coverage, and flexible light control. The wand can be placed on either side to match door configurations, improving usability in high-traffic spaces. They provide a balance of light diffusion and outdoor view when opened, making them suitable for home and office spaces that require wide coverage with easy maintenance.
LazBlinds Replacement Slats, White Textured (98″ W x 84″ L)

Premium fabric polyester slats with a textured finish replace aging or damaged vanes. They’re designed for easy sizing and quick installation, featuring pre-punched holes and weighted bottoms. You can trim to fit with household scissors, enabling a precise fit for sliding doors or large windows. The 98″ width allows ample coverage for substantial openings, and the room-darkening or light-filtering effect can be adjusted by pairing with other window treatments when complete darkness is required.
LazBlinds Replacement Slats (White Texture, 78″ W)

This set offers a white textured fabric slat option that is easy to size and install—pre-punched holes and weighted bottoms simplify hanging. It provides a room-darkening effect by filtering a portion of the light while preserving privacy. The 78″ W by 84″ L size fits standard large window systems or sliding configurations, and the slats can be trimmed to achieve a tailored fit without specialized tools.
LazBlinds Room Darkening Slats, 82.5″ x 3.5″

Packaged as 25 replacement slats in a longer 82.5″ length, these slats are designed to trim to fit precisely. They are made from durable polyester with a textured finish to resist fading and cracking. The room-darkening fabric reduces 60-80% of sunlight, helpful for reducing glare in living rooms and bedrooms while preserving some visibility to the outside world when tilted open.
LazBlinds Replacement Slats (White Texture, 78″ W)

This set features the same premium fabric material and easy-cut design as the 98″ alternative but in a 78″ width with 84″ length. The textured white slats provide a stylish, soft-diffused light and reliable privacy. Installation remains straightforward with pre-punched holes and weighted bottoms, allowing homeowners to trim to fit without specialized tools.
Buying Guide
- Material and finish: Choose vinyl for low maintenance and easier cleaning, or polyester fabric for a softer look and better light diffusion. White textured finishes offer a modern aesthetic that complements many decors.
- Light control vs. privacy: If you need strong privacy or room darkening, consider slats with room-darkening capabilities or pair with curtains for complete darkness. For soft daylight, opt for sheer-like or light-filtering fabrics.
- Mounting style: Inside mounts preserve a cleaner window reveal, while outside mounts can cover trims and create a more substantial window treatment. Ensure headrail width matches your opening.
- Ease of installation: Replacement slats should be easy to trim and install with basic tools. Check pre-punched holes and weighted bottoms for quick setup.
- Maintenance: Fabric slats may attract dust; vinyl is generally easier to wipe clean. Consider washable or wipe-clean options for high-traffic areas.
- Safety: Cordless or wand-operated designs reduce child and pet hazards. Cordless options are especially desirable in bedrooms or living areas with kids.
- Aesthetics and room context: White or white-textured blinds blend seamlessly with modern, minimalist, or coastal interiors. For room dividers, ensure the slat spacing and opacity align with the desired level of transparency.
- Sizing considerations: Accurately measure width at the opening and height to ensure the headrail and vane lengths provide full coverage. For open-doorways, consider extra width to avoid gaps.
