B-Line Eaton series imperial cable tray and ladder, 4" Height, 43.375" Length, 12" Width, Series 2-5 horizontal bend, Aluminum, 45° Angle, 48" Radius

Bend radius is driven by the minimum bending radius of the cable you are pulling. Large power and fiber cables need a wide sweep to avoid damaging insulation and conductors, and a 48 inch radius bend like the 4A-12-45HB48 gives that room. If your run carries small control or instrumentation cable, a tighter radius fitting saves space and cost. Check the cable manufacturer's minimum bend radius against the 48 inch figure before you commit to the layout.

This bend is aluminum, which is the usual pick where weight and corrosion resistance matter, outdoor and coastal runs, wastewater, food plants, and anywhere the crew is handling fittings up a ladder. Steel tray is chosen where higher load capacity or lower material cost governs. Whichever you pick, the fitting has to match the straight sections, so an aluminum bend belongs in an aluminum run.

What you are ordering under model 4A-12-45HB48 is the aluminum horizontal bend itself. Splice plates, bolts, and hangers are separate line items on cable tray jobs, so include connectors for both ends of the fitting and support hardware in your takeoff.

No. A horizontal bend such as the 4A-12-45HB48 turns the run left or right while the tray stays flat. To go up or down over an obstruction or into a wall penetration you need a vertical inside or outside elbow instead. Getting these confused is the most common ordering mistake on a tray package, so map each direction change on the drawing before you order.

The fitting itself weighs 10.757 lb, so one person can set it. That is fitting weight only, dead load on your supports still has to account for cable fill, and the 43.375 inch length of the sweep means you want a hanger picking up each end of the bend rather than relying on the adjoining straights alone.

Yes, CE certification is listed for this aluminum horizontal bend. That is the only marking on record for it, so if your submittal also calls for a specific load class or other listing, verify that separately against the series data for your run.
