CHICOLOGY Vertical Blinds are a practical, modern solution for sliding glass doors and patio doors. The cordless design uses a sturdy wand for easy daily use: rotate the wand to tilt the louvers for privacy and light control, and use the wand to traverse the blinds open or closed. The headrail is reversible so you can choose whether the louvers stack to the left or right during installation. Size note: 78 in W x 84 in H is the finished blind size and the headrail width you receive. Inside mounts may show side light gaps if your opening is wider than the blind; outside mounts can reduce gaps by adding overlap. For inside mounting, position the clip hole at least 2 inches away from the door or wall to allow full louver rotation. Included: headrail, 25 louvers, wand, matching valance (with clips/corners/returns), mounting brackets, screws, and wall anchors. Limited 1-year warranty.
