The New "Security" Insulator
The accompanying illustration shows a novel form of insulator about to be introduced by the Security Insulator Co., of 136 Liberty street. As will be readily understood, the wire is easily and quickly adjusted, and is securely held in position without injury to the insulation. The wire is pressed into the groove and held by the cap, while a cam movement allows different sizes of wire to be held equally well.

| The "Security" Insulator. |
This insulator entirely obviates the necessity of tie wires, thus effecting a great saving of both time and labor in wiring. The insulator here illustrated, which is full size, will take wire ranging from 1/8 to 3/8 inch. Other sizes are made to suit various requirements. They are made of the best vitrified and non-absorbent porcelain, and are as durable as they are simple and effective.
