    Ralph's Industrial is a great place for the sewing professional. We have had an ongoing relationship with the business for the last 5 years and they have helped us keep our company running. From new to used machines, repairs and equipment; this has been our one stop shop. I would highly recommend Ralph's Industrial to any fellow industry professional.

    These guys have crazy knowledge! Jack and Joe were awesome to recommend a machine that worked for a variety of our needs. Their service department has came out a few times too (due to my ignorance) and helped very well. Jack is like an encyclopedia of machine knowledge too. Definitely worth giving these guys a shot.

    I have been working with Ralphs for many years for all my sewing machine and sewing related needs. They have always been diligent with quick responses and technical help whenever I needed it. The best in the business and I’m lucky to have them.

    This place is awesome! I ordered a double needle thinking it was what I needed. I found out soon after I received it that it was the wrong machine for my shop. My mistake. I contacted my salesman Joe who helped me trade it in for a long arm. No hassle at all. I’m in Iowa so they sent a truck with the new machine & picked up the double needle. Very, very happy now! They really supported the sale all the way through!

    I can't thank Jaziel enough for going above and beyond to repair my double needle machine yesterday. He worked until the it was running smoothly again because he knew I was on a deadline to get orders out for Christmas. I am new to sewing and greatly appreciate Rueben always working with me and my lack of knowledge, Pat who is a whiz at timing and tension issues, and now Jaziel who is overly committed to the job and very knowledgeable. Thank you everyone in the service and repair department, you guys rock!!

    A few months ago I purchased a new Kingmax sewing machine and it's awesome! They helped me work through it and offered good support since. Great place to purchase and they take care of their customers.

    Everyone at Ralph’s was so helpful. Joe made sure I got the machine best suited for my needs. The guys went through the machine to make sure I knew how to use it and then loaded it up for me. Highly recommend for all your heavy duty/commercial sewing needs!
