NEW PRODUCTS------PLUG/RECEPTACLE ADAPTERS FOR THEATRE USE
Daniel Woodhead Company, Northbrook, Illinois, has
introduced a line of Adapters, allowing a theatre
technician to make instant connection to whatever form
of outlet he finds in the theatre.
Since many pieces of theatre lighting equipment are
supplied with pin connectors, it is often difficult to utilize
this equipment with non-theatrical electrical equipment.
The Daniel Woodhead Theatre Adapters offer a range of
plug and receptacle configurations to fit a variety of needs
in converting equipment to the conventional electrical
outlets.
The Woodhead Adapters are completely insulated, with
outer housing of rubber, internal parts molded of impact
resistant plastic. The neutral grey color of the adapter
housing blends into the background on stage or set.
Daniel Woodhead products are sold nationally through
electrical wholesalers, or write Daniel Woodhead
