The bottom casters should mount directly into this bottom shelf. This bottom shelf works with multiple Commercial Series Grills. Please provide us with the model number for your grill and we will be able to ensure that this part fits. This model number should be on the rating label, on the back towards the bottom of the grill, and also on the front cover of the product guide. The model number normally begins with 46.
