Electric Appliances & Apparatus
The electric outlet, illustrated below, stands on the floor instead of being set into the wall.
It is designed for factories, laboratories and other places where many outlets are required for machines, work tables or desks scattered all over the floor.
These outlets are especially adapted to a cellular type of floor construction which provides channels for electrical wires, thus making practically the whole floor available for electrical services.
