WIREMOLD Trenchduct Feeder SystemsTrenchduct Feeder System for Wallduct,Underfloor Duct, and Cellular RacewaysWiremold Trenchduct Feeder Systems arethe first choice for infloor distribution racewaysproviding large capacity, easy installation andfuture flexibility. Trenchduct also provides foreasy lay-in installation of wires and cables.The most common trenchduct application isas a feeder system for infloor raceway systemsincluding Walkerduct Underfloor Duct andWalkercell Cellular Raceway. Trenchduct isused in hospitals and health care facilities asa floor feeder for Wallduct Medical SystemsRaceway and can also be used as a standalone wire management system for commercialand retail applications where ease of accessand high capacity are primary concerns.Trenchduct is installed flush in a concrete floor providing easy access to wires and cablesFEATURES & BENEFITSn Large capacity. Trenchduct is designed to meet largecapacity requirements for single or multiple service systems.n No weld construction. Makes field modifications simpleand easy.n Flexible construction. Trenchduct width, depth, numberof compartments and compartment widths can be designedto meet specific job requirements.n Reversible tile trim supplied with standard assemblies.Trim is reversed to expose tile trim leg eliminating theneed for additional parts. Covers are painted with primer paintonly and are not intended to be used without floor covering.n Covers are relocatable to any location along the trench.Eliminates the need to mark and reinstall cover plates inoriginal locations.n Dual prepour adjustment. Trenchduct can be leveled tothe screed depth using the leveling foot or coupling up to3/4" [19.1mm].n Future needs can be met without disturbance toflooring. Simply remove cover plates to make wiringchanges and additions as required.n cULus Listed. Trenchduct Feeder Systems are UL Listedto U.S. and Canadian safety standards.Trenchduct application usedas a feeder system forWalkercell Cellular Raceway.ED738R10 – Updated July 2014 – For latest specs visit www.legrand.us/wiremold
