Hi Mary Ellen, Thank you for your question. I did reach out to the manufacturer on your question and here is their response to you: "If you were looking at the model# 6173? The 6181 is only a cabinet. The weight capacity for the 6173 = Weight capacities Top shelf - 75 lbs Middle shelf - 15 lbs Lower shelf under other shelves -15 lbs Bucket platform/shelf - 50 lbs Bag frame/support 100 lbs (w/o bag platform accessory) Bag platform (in addition to using the bag frame support ) is 50 lbs. Please note that the bag frame/support will now go from 100 lbs to 50 lbs because the bag frame/support and the bag platform split the load when using both Adding all the weights up based on a static condition, we have a 255 lb cart. In a dynamic condition where the user is pushing the cart we then have a maximum vertical static loading of 255 lbs x a 30 degree angled downward force at the cart's handle. This translates to an 88lb force to push the cart forcing it to rack. This calculation takes into account caster friction on the floor.. Each caster is required to take a 64 lb loading." Hope this information helps.
The measurement of this item is: Length - 20 inches Width - 16 inches
The height between the base and the cabinet is 14".
