A Simple Cleat.
Herbert C. Wirt of Boston devised the simple little insulator shown in the cut. It may be constructed of wood or porcelain. It is shaped, as shown like a block, having its longer side adapted to rest against the wall or ceiling. This cleat has at either end a knob projecting horizontally parallel with the side which rests against the wall. The knobs have each a contracted neck, so that the wire may be wound around them.
It is claimed that the use of this form of cleat greatly expedites the stringing of wires. The wires when in place are held at a slight distance from the wall, and their insulation will not be affected by any moisture on the wall, as is the case with the ordinary form of cleat where the wires are stretched in contact the wall.
