Grindstone United  is a line of clothes designed for the Great American Worker. We are proud to print and design some of the best products in the country. This is a subsidiary of Zubie Wear. Zubie Wear was founded in 1997, and has grown to become one of the largest union screen printing companies in the country. We started with a simple idea; "Excellent workmanship at a fair price, produced by union labor". That philosophy has worked well for us and we are now a major supplier of GCC/IBT printed products and apparel to unions across the United States and Canada.

Our people make us great. From our friendly sales staff to our quality obsessed production team, we have some of the most knowledgeable and skilled employees ever assembled in one place, all with one simple goal in mind; total customer satisfaction.

State-of-the-art production facilities. We have over 10,000 square feet of modern pre-press and printing equipment to meet all of your screen printing needs. Automated equipment and skilled press operators insure that you get a consistent quality product every time you order.

We are also proud to serve the ICWU members across the great United States of America with top of the line products and fantastic designs. Thank you for the opportunity to serve you. A percentage of all ICWU merchandise is proudly donated back to for worthwhile causes.
