New Vulca Bushings.
The new Vulca bushings of the New York Insulated Wire company have been perfected and are now on the market. The accompanying cut shows the general appearance of these bushings. They are made in several sizes, ranging from 5-19 to 3/4 inch in inside diameter and 6 to 12 inches outside lengths. These bushings, it is
claimed, are moisture-proof, non-inflammable and are not affected by the action of Portland or hydraulic cements. They have been approved by the National Board of Fire Underwriters and the Chicago fire department.
