ing members, which adds both to its strength and safety. The iiooring of the platform is made of heavy expanded metal grating to provide sure footing.

The platform and mounting frame are welded together, and shipped as one complete unit, eliminating the necessity for any parts assembly on the job. The companion half of the mounting clamp for the safety platform is welded to the pole. Thus it is only necessary to bolt the two parts together. This arrangement offers a practical and safe means for servicing equipment at high mounting heights with ordinary labor.

One of the advantages of the Union Metal Monotube Hoodlighting pole is its

adaptability to complete assembly on the ground prior to erection. Here is a new departure from the old method of erecting the bare pole first, and eliminates entirely the hazard of men Working high in the air to assemble the various parts.

The poles can be completely wired, and the lights mounted and properly positioned on the ground before erection. The erecting crane lifts the pole into place on the anchor bolts embedded in the foundation. These heavy two and one half inch steel anchor rods are supplied with adjusting nuts for plumbing the pole after it is placed on the foundation. No guying of any kind is required.

Special attention has been paid to wiring convenience and easy access to all lights. The lights can be easily cleaned and serviced from the safety platform, and this work can be done by unskilled labor. Servicing and cleaning of lights is probably necessary only once a year.

Poles are furnished with supports for mounting transformers and distribution boxes as well as primary fused cutouts.

Pole steps commence approximately 12 feet from the ground line, and double steps are installed at necessary locations.

Hand holes and wiring outlets are provided at strategic locations to facilitate wiring. A cable support is welded into the top of the pole.

Because of varying soil conditions, it is impossible to determine the exact size and shape of the foundation. The company has, however, prepared suggestions for adequate foundations which can be used as a guide by oneis local contractor, following the determination of the local soil conditions.
