A weighing device draft shield having at least one linearly displaceable wall (e.g., side wall) for allowing access into a weighing compartment of the weighing device. Each displaceable wall is provided with a top guide rail that passes through a roller assembly. Each displaceable wall is suspended in a substantially vertical position by engagement of its guide rail with a corresponding roller assembly. An adjustment element may be provided to alter the position of certain rollers of the roller assembly such that the orientation of the corresponding guide rail and attached displaceable wall may be adjusted to account for dimensional variations of the enclosure, etc. The use of a guide rail and roller assembly facilitates displaceable wall movement by substantially eliminating sliding friction.
