TRUE SIZE 78" W x 84" H – Finished blind size with a 78" headrail/track width. If your opening is wider than 78", choose an outside mount so the headrail overlaps the frame and closes any side gaps; inside mounts fit within the opening itself. ONE WAND, TWO MOTIONS – Turn the wand to tilt the PVC louvers for light and privacy, or move it side to side to traverse the panels open and closed. No cords to manage. REVERSIBLE STACK, YOUR CHOICE – The headrail can be set to stack left or right at installation, so you pick the direction that fits your door and room layout. EVERYTHING TO INSTALL – Headrail, 25 PVC louvers, wand, matching valance with clips/corners, mounting brackets, screws, and wall anchors are included. If anything arrives missing or damaged, contact us through your Amazon order first so we can send a replacement part directly. EASY-CARE VINYL, LIGHT CONTROL – 3.5" PVC louvers wipe clean with a damp cloth. Closed, they reduce light and add privacy for everyday use; they are not a full blackout product, so expect some light at the seams and edges. BUILT FOR FRENCH & SLIDING GLASS DOORS – Vertical blinds are the standard choice for wide door openings; the 78" track clears typical sliding and French door widths without blocking the walkway when panels are stacked open. COORDINATED VALANCE INCLUDED – A matching valance snaps onto the headrail with the included clips and corners, so the mounting hardware is hidden and the finished look matches the panels. MULTI-ROOM VERSATILITY – Works over sliding glass doors, patio doors, and French doors, or as a room divider in living rooms, bedrooms, and dining areas. DURABLE PVC CONSTRUCTION – Rigid 3.5" louvers resist warping and fading better than fabric vertical blinds and won't absorb moisture near doors and windows.
