About Us

Carlson Capitol is located in Rockford, Illinois, and was founded in 1945 under Capitol Tool & Die Works, Inc. In 1981, Capitol Tool & Die purchased the assets of W.G. Carlson & Sons. The lid support product line came with the purchase of W.G. Carlson. Our name was then changed to DBA Carlson Capitol Manufacturing Company.

Through the years, we have continued to produce quality metal stampings, and lid supports closures to meet the needs of our customers. As a result of the excellent standards of our stampings, we gradually developed the lid support system and found ready acceptance of this quality product. We are now recognized as having the most dependable closure of its kind in the world marketplace.

Carlson Capitol offers a wide variety of production equipment to produce delicate quality stampings from product print to a finished piece. Our facility includes a fully equipped tool room, press capacity from 10-100 tons, and equipment to handle steel coil stock.

Besides producing metal stampings for a variety of customers, our lid support is our product line. Because the lid support is our only product line, we have been able to customize our products. We have different brackets, cams, rivets, slides, and plating.
