Hi Folks....I hope you're all well. I need a little input..if you don't mind. And I apologize that it might seem mundane. Anway....casters. If a 4x10 cabinet weighs less than 70 pounds, and it has a "smallish" size for a 4x10, does it need to have casters? The reason I ask is because it is tough to find a good "solution" for casters. They are either expensive, a pain to use or fragile and ineffective. Thanks for any input.
