Dunton & Field tree insulator meeting with success

Dunton & Field, 117 Main street, Cambridge, Mass., are meeting with tremendous success with their tree insulators. The fact that these insulators are supported on swinging arms, as shown in the accompanying cut, allows perfect freedom of the branches of the trees to sway in any kind of a wind storm without straining the wires or the insulation on the latter. These insulators have become the standard in central station practice for all classes of tree construction, and in every case where they have been installed they have given perfect satisfaction. There is hardly a central station in the country which has used these insulators, that has not ordered additional supplies whenever its lines have been extended. The above company will be glad to send you a circular and prices regarding these insulators.
