Abstract
A device for a track- or rail-mounted closure drive assembly can include a lever and cam arrangement configured to drive an engagement member between an engaged position and a disengaged position, the engaged position allowing motor drive of a closure and the disengaged position disconnecting the drive from the motor to the closure; and a rotating body including one or more camming surfaces and one or more peripheral surfaces, the peripheral surfaces including visual indicia to indicate to a user an orientation of the one or more camming surfaces and hence whether the engagement member is in the engaged position or the disengaged position.
