High Insulation Brackets.

The system of high insulation brackets shown in the cuts has recently been completed by the Electrical Supply company of Chicago. By careful designing the new forms have been made neater in appearance, and at the same time stronger than the old ones. The castings are split at the screw, so that the danger that an insulator may be broken by the expansion of the metal is prevented. It is often necessary to attach the brackets in places where one man must work at a disadvantage. It will be noted in the cuts there are slots instead of screw holes. The screws or bolts for one side are driven in

first; the bracket is then hooked on and supported in position while the remaining fasteners are inserted. This construction not only simplifies the application of the brackets, but makes their removal an easy matter. There is a great variety of forms; brackets to go above, below or around all sorts of wiring obstacles and yet hold the insulators always in their only effective position — that is exactly perpendicular.
