Frey Manufacturing Corporation was established in 1981 to provide a quality signal mounting system that worked. Previous to starting Frey Manufacturing, Bob Frey, President of FMC, was working on a project for street lighting as an electrical designer. Through the course of meetings it became apparent that MnDOT was having trouble keeping their signals aligned with the set screw style system they were using. Bob offered to create a design that could solve the problems they were struggling with and came up with the 32A plumbizer. The 32A plumbizer uses two tapered washers to adjust the pitch and level of the signals. Then it is bolted in place rather than using set screws.Since the creation of the 32A plumbizer we have come up with a new style of plumbizers that uses a ball and socket to adjust pitch and level rather than the tapered washers. These plumbizer are called the 35E and 45V. Since FMC has been in business we have created a complete line of mounting equipment to offer for almost any application.Frey Manufacturing provides products that work and are virtually maintenance free. However, they can only be used if they are specified on your Approved Products List in your state.
