The Allied Tube & Conduit PVC Tube (vendor part 882767, Millennium part 598281) is a 3 in x 29 in Schedule 40 gray section used as a short conduit stub or fitting extension on duct bank and conduit installations. Its short length makes it useful for tight transitions at handholes, risers and cabinet stub-ups where a full 10 or 20 ft stick would be wasteful. Corrosion-resistant PVC construction holds up to buried and outdoor service conditions. Millennium also stocks matching Schedule 40 elbows and conduit runs in the same 3 in system.
