New American Insulator Co. insulator shown in exhibition

THE McIntosh-Huntington Company, a large Cleveland concern, made an exhibit jointly with the Ericsson Telephone Company of its several telephone specialties, which it handles, including Roebling cables, McIntosh sound-proof booths, Stambaugh land anchors and a complete line of construction tools. A new glass insulating tube, brought out by the American Insulator Company, was shown the first time. It is designed to pass thru a hole in the center of the cross-arm, which does not weaken the arm nearly as much as the pinholes. It does, of course, do away with the ordinary pin insulator.
