For an inside mount you will receive two brackets. One has a slotted hole and the other just has a round hole in middle. The slotted bracket is the control end bracket which mounts on the left side (when facing the window). The one with a round hole mounts on right.
Be sure to mount the top edge of the brackets at least 1/4" from top of window (so shade roll doesn't hit top of window). The oval install holes should face the bottom of window. Install the included screws in both the top and bottom holes.
Hanging the shade - Place the pin side of the shade (right end) into the round hole first, then slip the control (flat) end into it's bracket.
