Connect the brackets by sliding the metal and plastic bracket pieces together. They fit together tightly.
Measure your curtain lengths including the curtain rod pocket. Decide where you want the curtains to end, such as at the bottom of the windowsill or at the floor.
Screw the brackets into the walls at the desired height by measuring up from the ideal curtain height. Use screws that are appropriate for the wall's material such as drywall screws for drywall and masonry bolts for masonry. If you can't find a stud to screw into, use drywall anchors with your screws.
Attach a center bracket near the corner. Ensure all the brackets are aligned, using a level.
Set the rods on the floor and slide them so they are adjusted to the approximate needed length. Slide each end of the rod into the end caps.
Attach a corner connector to the center end of each rod and connect the piece together. Hook the center onto the center bracket.
Feed the curtain rod into the curtain's pocket until it is neatly positioned.
Hook the curtain rod onto the wall brackets by angling the end up, hooking it on the bracket's hook and sliding it down into place. It is easier to put the curtain rod on the brackets with the help of a second person.
