Before proceeding with the installation, decide on how far from the upper window frame you want your Custom Curtain rod to be. Hint: it depends on the length of your curtains, and how big you want your window to look. Though it\u2019s common to install a curtain rod halfway between the ceiling and the upper part of the window frame, please bear in mind that the closer to the ceiling you install your curtain rod, the taller your room will look. Once you have decided on where to position the brackets, do the following:Use a pencil to mark the top holes of the curtain rod brackets;Place the top hole of the bracket over the top point and mark the bottom point;Make sure that the marks are level across the opening;Drill the marked points.If you hit a stud, drill 1\/8-inch holes and install screws through the brackets. If the wall is hollow, make 3\/16-inch holes, push or hammer plastic anchors into the holes, and install screws through the brackets.Insert the achors and install the screws through the bracketsWe are one of the China curtain pole factory, welcome to your come and purchase!
