  • Power Distribution Solutions
    UNION CONNECTOR POWER DISTRIBUTION SOLUTIONS Since 1929, Union Connector has manufactured electrical products for the entertainment industry. The company was founded by William “Bill” Wolpert, an IATSE Local 1 stagehand. The company is now owned by a third generation of Wolperts, the grandsons of William. Manufacturing the ‘stage pin’ connector was the mainstay of the company for almost forty years. In that time, Union Connector became the primary manufacturer of the standard theatrical wiring device. It is safe to say that almost every theatre from Broadway to Hollywood has used pin connectors made by Union Connector. In the 1980’s and 90’s, Union Connector dedicated considerable resources to research and development of new products. Some of these have become the modern standards for power distribution in the industry. Several patents were awarded, including the polybox™ power distribution box and the revolutionary SafeCam™ outlet system. The company switch Union designed during this time is now the standard type specified for theatres, convention centers and studios nationwide. The millennium found Union Connector continuing to evolve into a modern manufacturing company. Major investments were made in CNC fabricating machinery, computerized warehouse facilities and 3-D CAD/CAM design engineering. Power distribution equipment for entertainment lighting/audio is still the mainstay of Union’s product line — much of it custom designed and built for specific applications and projects. But Union now has the ability to fabricate specialty equipment for a variety of other applications as well. Spacelights, data center power distribution, grip equipment and custom machined components are just some of the other products Union Connector now manufactures.
