Offered in left or right configurations, T&B® Cable Tray Helix™ Fittings ease transitions between horizontal and vertical cable tray runs, especially in confined areas and near walls. Units come in aluminum, pre-galvanized steel, and stainless steel in 12 and 24 in. widths with 6 in. side rails. Available pre-assembled, fittings enable installers to secure and organize cable runs without needing to position cable tray assembly to make room for transitional fittings.
