The Allied Tube & Conduit PVC Elbow (vendor part 925008, Millennium part 525415) is a 4 in hub, 29 in long, UL651-rated bend used to route larger conduit runs around obstacles or up into risers and cabinets. Its extended sweep length keeps the bend radius wide enough for cable pulls without excess friction on 4 in duct. Gray PVC construction matches standard Schedule 40 conduit systems for consistent appearance and performance. Millennium also stocks the matching 4 in hub conduit and LB fittings for the same conduit run.
