“It was a great decision to hire Warehouse Equipment for the new racking project in CVG, Ohio. Chad and his team provided an excellent service, and they even improve the delivery and installation dates, allowing the client to load the space earlier than expected. I will recommend using them for warehouse and racking projects.”
