1 S and ast Hub evice oxes UNILTS for use with Threaded Rigid onduit and IM. ll device boxes have ridge top construction. pplications ccommodate wiring devices such as switches and receptacles. Provide excellent service in areas where boxes are subject to rough usage. Serve as pull boxes for conductors. Permit access to conductors for maintenance. Provide openings for making splices. llow connections for branch conduit runs. lank bodies for special conduit entrance arrangements. eatures orrosion-resistant ideal for indoor and outdoor installations. Weatherproof, raintight and dust-tight when used with cast gasketed covers. S and boxes take standard flush wiring devices. boxes take devices exceeding 1-5/8 in depth under fastening ears. Malleable iron for high tensile strength and ductility provides greater resistance to impact and shock. oth malleable iron and aluminum boxes have ridge top construction for positive cover/gasket/box fit. ccurately tapped, tapered threads for tight, rigid joints, ground continuity. omplete selection of covers, receptacles, plugs, gaskets and accessories. overs have captive stainless steel screws to speed installation, prevent "freezing" of screws. Ground screw at top of box for easy access. ast Hub oxes vailable in single, two, three and four gang and tandem. Smooth, rounded integral bushing in each hub protects conductor insulation. lank odies for razed Hubs or rill and Tapped ntries vailable in single, two, three and four gang boxes. rill and tapped entries. razed threaded hubs for threaded conduit from thru 1- and brazed union hubs from thru 1-1/4. Smooth, rounded integral bushing in each hub protects conductor insulation. Ground screw at top of box for easy access. Standard Materials ast hub device boxes and boxes for drilling and tapping: malleable iron or copperfree (4/10 of 1% max.) aluminum razed hubs: malleable iron overs: malleable iron, steel, or copperfree (4/10 of 1% max.) aluminum Standard inishes Malleable iron boxes and covers: triple-coat (1) zinc electroplate, (2) chromate, and (3) aluminum polymer enamel luminum boxes and covers: epoxy powder coat Steel covers: zinc electroplate Screws: stainless steel Options nclosures drilled for 347 Volt devices. dd suffix Gasket is designed so that it wraps around ridge top of ppleton aluminum or malleable iron device box.

It is possible to place more than five hubs on the top and bottom of three and four-gang Unilets. Look at the chart below for the maximum hub diameter and the minimum hub spacing distance. This chart, together with the Unilet dimensions will enable you to figure the maximum number of hubs which may be used.
