B-Line Eaton series Flex tray wire basket tray, Controlled interior reended application, Black powder coat finish, Steel, 8.2" actual area inside tray

The Eaton B-Line FT2X4X10 BLE is a 2 inch deep flex tray, 4 inches wide, in a 118.312 inch (roughly 10 foot) stick. Overall height measures 2.38 inches, which is the figure to use when you are calculating clearance above a ceiling grid or under a slab, not the 2 inch nominal loading depth.

No. The black powder coat FT2X4X10 is specified for controlled interior applications only. Powder coat over steel is a finish for conditioned, dry indoor spaces such as data rooms, office ceilings, and equipment rooms. For exterior runs, parking structures, or damp and corrosive environments, move to a hot dip galvanized or stainless basket tray instead.

A 2 inch deep wire basket like this one is for low voltage and communications cabling where you want free air ventilation, easy drop-outs anywhere along the run, and field cutting with a bolt cutter rather than a fabricated fitting. Solid bottom tray is the choice when you need physical protection or EMI shielding for the bundle; ladder tray is for heavy power feeders with long support spans. At 4 inches wide and 2 inches deep this is a small, branch-level pathway, not a backbone riser.

Usable cross section inside the FT2X4X10 is listed at 8.2 square inches. Divide that by the cross sectional area of the cable you are running and derate for the fill percentage your spec calls out. For reference, 8.2 square inches of usable area is a branch run pathway, typically a few dozen Cat 6 cables at a conservative fill, not a main telecom backbone.

Yes, that is the intended environment. Steel construction with a black powder coat and a controlled interior application rating fits conditioned server rooms, MDF and IDF closets, and above-ceiling office runs. Black is commonly specified in those spaces so the tray disappears against an open plenum ceiling.

What ships is the tray section itself, model FT2X4X10 BLE, a single 4 inch wide by 2 inch deep length. Splice washers or couplers, threaded rod, trapeze or wall brackets, hold down clamps, and bonding jumpers are ordered separately from the B-Line accessory line. Plan on one splice connection per joint and supports at the interval your spec requires.

CE is the marking listed for this B-Line flex tray. If your submittal requires a UL classification or a specific NEMA VE designation, that has to be confirmed against the Eaton submittal sheet for the series, since CE is the only marking carried on the product record.
