Wiring can be rundirectly from the top of the duct to theoutlet stations, eliminating servicefittings that protrude above the floor.Removable covers are 3/16" thick andlock into the track of the trenchpreventing deflection under heavyloads.Removable covers allow freeaccess to wiring and can be placedanywhere along the duct for easy wireexit relocation.Applications Commercial BuildingsRetail OutletsOffice BuildingsSchools, UniversitiesShopping Centers24c2005 Filges www.filgesco.com
Raceway SolutionsTMTrench Duct The leveling screws provide verticaladjustment of the duct prior toconcrete pour; this allows the duct tobe leveled to the screed line so onlyone pour is requiredTileTrimThreadedGrooveDuct FrameDuct frame includes fixed metalpartitions that create multiplecompartments in the duct. This featurepermits a single duct to distributepower, electronics andcommunications. Duct with fewerpartitions is available to meet yourspecifications and can be located instrategic places to meet specialdistribution requirements.The duct frame is available in avariety of sizes. The frame is of 14gauge galvanized steel and issupplied in standard 6' lengths. It canbe cut to length which increases fieldflexibility and eliminates the need forordering specialty fabricated material. The aluminum tile trim provides afinished edge for the tile, assists incutting, and can be reversed whenthe trim is not required; can bereversed when carpet is used The extruded rubber gasket acts asa cushion, sound dampener andmoisture barrier between the coverplate and the duct; meets U.L.moptight requirementsDuct Support AssemblyThe unique duct support assemblyprovides one time leveling capabilityand acts as a splice for duct sections.The assembly consists of the levelingscrew clip, mounting plate, andleveling screws, and is independent ofthe final support of the duct.LevelingScrew ClipLevelingScrewPartitionTrackThe track of the structural assemblyintegrates the base aluminum profilewith the tile trim, extruded rubber strip,and the duct support assembly. Thetrack also provides the screed line forthe concrete. The aluminum profile accepts andholds the duct frame, rubbercushion, and cover plate screws inaddition to supporting the coverplate; it also acts as a runner for theleveling screw clips.MountingPlateCarpetTrimRubber StripAluminumProfileCoverThe cover plates for the RacewaySolutions Trench Duct are horizontallyadjustable to any point along the duct.The 3/16" thick cover plates come instandard 24" lengths — three areprovided per 6' duct section. A 1/4"thick cover plate is also available as acustomer option.A special threaded groove on thetrack accepts the cover plate screwsat any point along the duct, providingthe cover unlimited adjustment. Thisspecial design relieves the installerfrom matching the duct frame sectionswith the covers, eliminating fieldcutting in most instances. This cansubstantially reduce installation andmaintenance costs.The cable exit may be installed onan exit fitting cover allowing cable tobe easily pulled out and activated.The cable exit is reversible to provideaccessibility from either direction. Thestandard cover plates may beremoved and exit fitting coversinstalled for the cable exit.Leveling screw allows for 1" adjustment. The leveling screw clip integrateswith the track and provides fulladjustment along the length of theduct; it also acts as the splice forduct sections The heavy gauge mounting platefastens duct to metal deck,roughslab,or wood/metal forms prior topouring concrete; it adjusts to meetmost floor and installationrequirements.25c2005 Filges www.filgesco.com

Raceway SolutionsTMTrench Duct SpecificationsSpecificationsRaceway Solution Trench Duct has beendesigned to offer the most completein-floor wire management system forcomputer terminals. The particular usefor retail store checkout countersusing scanners has been selected forthis catalog. Its potential capacity,unlimited point-of-delivery, and wirecompartmentalization provide flexibilityfor current requirements as well asfuture needs.Raceway Solution Trench Duct maybe specified for stores that are beingretrofitted for the use of scanners aswell as new stores.The specifier should consider thefollowing:1. The two outer compartments forthe 12” size (2½" deep) have 6.6 in2wiring capacity. (This provides greatercapacity than 2½" conduit). Two powercompartments are offered: One for computer dedicated circuits One for general purpose powercomputer cables and the other forintercommunication or telephone.Depending on the sensitivity of thesystem, these two compartments maybe used interchangeably.4. Covers may be adjusted to anylocation as well as the exit fittingcovers. Therefore, predetermination ofexit locations is not required andfuture access to the wiring at anylocation is available.5. To feed the computer location orcheckout counter, service fittings withreceptacles may be used or the exitfitting cover hard wired to the point ofdelivery. For example, flexible metallicconduit or liquidtight conduit may beused between the exit fitting coverand a utility box with a receptacledirectly under the counter.6. Cable exit caps may be used forcomputer, telephone, or intercommunication cables. In certain cases,armored or other approved cable maybe permitted with the cable exit cap.2. The outer compartments shouldbe chosen for the power since runs ofconduit can be tapped off the sides ofthe duct (¾" and 1") to speciallyplaced floor boxes or stubbed out ofthe concrete to provide power atlocations to the left or right of thetrench.3. The inside compartments of thefour compartment 12" wide duct(OKA/B12-4C) each have 6.6 in2wiring capacity in a cross-sectionalarea that is 3.0" x 2¼" on sides. Thelargest electronic connector can passthrough this area and exit with ease.One of these can be designated for30c2005 Filges www.filgesco.com
