The History Behind Romberg Co. and Tag-Lok

Tag-Lok was originally developed by Mark Romberger, a United States military veteran and experienced electrical lineman who recognized the need for a practical, durable way to protect safety tags in demanding work environments.

Drawing on his firsthand experience in the electrical industry, Mark developed a reusable safety tag holder designed to help keep important warning and identification information protected and visible.

Some original Tag-Lok devices carry molded markings referencing Romberg Co. USA, along with model numbers such as THO-2283 and THO-3383. These markings connect today’s products to the original design and its American manufacturing roots.

Today, Tag-Lok products are supplied by J&J LOTO, LLC, continuing the tradition of manufacturing these safety tag holders in the United States.

While the company has evolved over the years, the commitment to providing practical, durable, American-made safety products remains.
