A variable doorstop selectively determines the opening distance of an access door of a merchandising machine, the access door being mounted in channels of the merchandising machine to be slidable between an open position wherein the access door permits access to a compartment aligned therewith and a closed position wherein access to the compartment is restricted. The doorstop comprises a hinge assembly including at least one hinge. Each hinge has a backing plate for mounting the hinge on the merchandising machine and at least one abutment plate. The at least one abutment plate is rotatable about a pin of the hinge to selectively pivot the abutment plate from a non-engagement position in which the abutment plate is positioned away from the path of the access door to an engagement position in which the abutment plate is in the path of the access door. The abutment plate in the engagement position establishes the open position by restricting the access door from sliding further along the channels past the abutment plate in the engagement position as the access door is slid from the closed position to the open position.
