New Insulator for Interior Work.
The accompanying illustration shows a new form of porcelain insulator for interior construction, which holds a wire or cable securely in place without the necessity for binding it or injuring the insulation in any way. This results in a saving of both material and labor and reduces the cost of installation.
The new insulator is made by the Porak-Isolatoren-Unternehmung, Wiedener Gurtel 28, Vienna, Austria, by whom applications for patents have been made in all civilized countries.
