Installing blinds inside brackets requires careful attention to detail. Start by measuring the width and length of your window frame to determine the size of blinds you need. Once you have determined this, slide each side of the blinds into each bracket evenly, making sure they fit snugly. Check to ensure that the blinds are level by using a level tool or simply by visually observing their alignment with the window frame. Make any necessary adjustments before locking them into place by pushing down on each bracket's tab until you hear or feel a click.
