B-Line Eaton series imperial cable tray and ladder - Length 48 in, Width 18 in, Height 4 in

Yes. The 4A-18-09-HX12 tray section is UL Classified, which is the listing electrical inspectors look for when cable tray is used as an equipment grounding conductor path or carries power and control cable in a commercial or industrial installation.

Match on three things: nominal width, side rail height, and the manufacturer's series. This section is 18 inches wide with a 4 inch rail, ordered as 4A-18-09-HX12 in the Eaton B-Line imperial line. If the existing run is the same B-Line series at 18 inch by 4 inch, the rails and splice hole pattern line up. Tray from a different series or a different maker will usually need a transition splice rather than a direct bolt-up, even when the nominal width matches.

Ladder tray, which is what the B-Line 4A-18-09-HX12 is, leaves open rungs between the side rails so cable can ventilate and drop out anywhere along the run. That suits power and large control cable in plant and data rooms. Solid bottom or ventilated trough is the choice when you need to support small diameter cable that would sag between rungs, or where you want debris kept off the cable. Pick ladder for heat dissipation and drop flexibility, solid bottom for fine cable support.

What ships is the straight 48 inch ladder tray section itself. Splice plates, bolt kits, trapeze or wall bracket supports, and any elbows, tees or reducers for changes of direction are separate line items. Take off the straight footage first, then add one splice kit per joint between sections and the fittings for each turn or elevation change.
