In severely corrosive en-vironments, stainless steel cablescan be supplied.COMPLETE FACTORYPRE-WIRING.

The main porver cable and thccables for each luminaire are fac-tory ple-rvired into the mountingrins, avoidins the need for fieid

rviring. Thelc is no electro-me-chanical disconnect at the poletop, rvhich r.ould requirc on-sitcu'iring to top-mounted contactsand periodic inspection and main-tenance. Insteurd. the disconnectfor the main porver cable is located at the base of the pole alongwith main electrical connections.This allorvs rapid and conr-enientservicing and installation.GROUND-LEVEL TESTING.All cables - electrical and hoist-ing-can be inspected or replacedfrom the ground. In addition, aweatherproof pou'er leceptacle isprovided in the mounting ring,allo*ing the luminaires to be energized for testing lamps and bal-lasts *'hile at ground level. Thismakes it unnecessary to rcturnthe luminaire ring to the pole topin order to check electricai cir-cuits.MANUALLY PORTABLEPOWEF UNIT OPERATESWINCH.

A heavy duty reversing clectricmotor, coupled with a torque lim-iter, supplies all necessary driv-

ing po*,er to the winch. Themotor mounting f rame assemblyis proYided s'ith a remote controlto cnable the operator to stand15'from the pole. This assembiyis simply strapped io the base ofthe pole with a quick-connect se-curing mechanism that can ac-commodate any size or shape pole.Lorvei'ing rate is approxi-matell'20 fect per minute; hoisting late for the heaviest assem-bl1. is apploximately 12 feet perminute.cHotcE oF 2 srzEs FtTsALL POLE DIAMETERS,

Since pole sizes of various man-ufacturers differ widelir, Holo-phane offers two basic lo*'eringsystem sizes: The LD,2 is de-signed for poles u,ith diametersof 24" or less and accommodatesfrom two to eight luminaires. TheLD-3 is designed for poles \a'ithdiameters ol 40" ot'less and accommodates up to ten luminaires.Both Holophane systems areavailable as separate componentsor in complete packages includ-ing pole, luminnires and log'eringsystem.
