The present invention relates to a variable spreader driver (10) for jointly opening a lift car door and a lift shaft door, which spreader driver can be mounted on the lift car door, comprising a pair of first and second gripping elements (16, 18) which extend essentially in parallel and vertically and which can be moved between an opened position, in which they are at a first horizontal distance from one another, and a closed position, in which they are at a second horizontal distance from one another, wherein the first horizontal distance is larger than the second horizontal distance; and an activation device (12) which is configured to move the first and the second engagement element (16, 18) between the opened and the closed position while maintaining their essential vertical extent. The spreader driver according to the invention also comprises a mounting plate (24) which is configured to be moved together with the second engagement element (18) and to bear the latter securely, for which purpose it comprises a multiplicity of circular drilled holes (24b) in a predefined arrangement; and the second engagement element (18) comprises a multiplicity of groups of circular drilled holes (18b) which are each aligned with one another according to the predefined arrangement, wherein according to the multiplicity of groups of circular drilled holes (18b) the second engagement element (18) can be mounted with different defined orientations on the mounting plate (24) by means of mounting elements (28).
