Dunton & Field seeing large demand for their tree insulator

Dunton & Field, of Cambridge, Mass., report a steadily increasing demand for their Dunton Tree Insulators, which have become the standard for this class of work. The manner in which these insulators allow of the free movement of the swaying limbs and branches of trees to which electric light and power wires are attached is almost human. The wires are held firmly to the insulators with no strain on the insulation and seem to the eye to be almost motionless while the limb to which it is attached may sway almost to breaking while the swinging arm and pin allow of every movement.
