Hello Roobahsox, Thanks for writing a review and we're sorry to have learned about your disappointment. Did you hear a clicking sound during the assembly? If not and if you haven't tried, you might want to try using a rubber mallet to gently tap the caster into the caster foot. Otherwise, you may return the product to Home Depot for an exchange in accordance with their return policy. If you have questions or concerns, you may call our Customer Service at 1-800-474-3443 from Monday to Friday between 8:00 AM to 5:00 PM Central Time and we'll be glad to assist you. Thanks, RIDGID
