Step-by-step instructions
Step 1
Measure the blind headrail, window recess, and curtain stack-back zone; confirm the existing frame can carry only the light hardware you select.
Step 2
Choose a curtain system that attaches to the vertical-blind headrail or uses a properly rated tension rod, keeping the blind controls unobstructed.
Step 3
Install the adapter or tension rod according to its load limit, then hang the blackout panel with the hem clear of the floor.
Step 4
Open and close the vertical blinds ten times, checking that the curtain cannot foul the tilt chain or emergency egress path.
Step 5
Add overlap at the sides and top, then photograph the final position so the rental can be restored without wall damage.
Do not block a required emergency egress window, overload a blind headrail, or use an un-rated rod above a bed or walkway.
