Left versus right

Thanks for posting. Good question! View the picture of both-handed versions of the S140-7 below. Note that the side that exposes the coil tape is meant to be facing inside the house. So for instance, the left-handed S140-7 in the picture is facing inside the house. The right-handed would be oriented the same way, or else the cam would not be facing the window sash! Both handed-versions could not be switched with one another, as the side that exposes the coil tape is meant to be facing inside the house. Let us know how this setup works for you.
