Glass floor tube insulator offered by Royal Electrical Specialty Company

A Safety Floor Insulator.

We illustrate on this page a new safety floor insulator which has been recently brought out and placed upon the market by the Royal Electrical Specialty Company, of this city. Its object is to take the place of hard rubber tubing for carrying wire through floor partitions. The insulator is of a fine quality of glass and has received the approval of the New York Board of Fire Underwriters. They are made in various sizes, ranging from three to six inches in length and are being extensively used by a large number of the electric light and motor companies throughout the country. They have also been employed quite largely as window tubes for the reception of heavy electric light wires, and have given good results in all their various applications. The latest form is made hexagonal to the extreme top of the head for convenience in insertion.
