Walkerduct® Underfloor Duct System includes two sizes of underfloor ducts - No.2 and No. 4 - for maximum flexibility. This allows you to match cable capacity to project demands by combining several ducts of different sizes in the same system. It's an ideal configuration for casinos, commercial offices, education, government, museums, and retail applications. Walkerduct features superior product construction, manufactured of 16-gauge galvannealed steel with continuous seam welds. It accepts a wide variety of service fittings, including flush and pedestal styles. Ducts are available with or without presets. Pro Series presets are rectangular and accommodate flush and pedestal service fittings while providing ample bend radius to ensure the integrity of fiber optic cable connections. IPS presets are round and offer smaller egress areas. These work with pedestal style activations and are ideal for furniture feed applications. See page 17 for more information on compatible service fittings. Walkerduct can be fed by junction boxes or by Trenchduct for larger cable capacity installations.
