B-Line Eaton series imperial cable tray and ladder, 6" Height, 51.000" Length, 24" Width, Series 2-5 vertical outside bend, Aluminum, 90° Angle, 48" R

Plan on roughly 51 inches of developed length through the fitting, which is the stated length of the 6A-24-90VO48, on a 48 inch bend radius turning a full 90 degrees. In practice that means the elevation change consumes about four feet of vertical rise plus the tray depth, so check headroom, duct, and structure before you set the hangers. Tight ceiling space usually calls for a smaller radius fitting instead.

A vertical outside bend carries the tray run up or over an obstruction so the cables ride on the outside of the curve, keeping tension off them as the run changes elevation. The Eaton B-Line 6A-24-90VO48 is a 90 degree vertical outside fitting with a 48 inch radius, so it turns the run through a full quarter turn. Use a vertical inside bend instead when the cables sit on the inside of the direction change, for example where a run drops down against a wall rather than crests over a beam.

Bend radius is driven by the cables, not the tray. Large power and fiber cables have a minimum bending radius that a tight fitting will violate, so a 48 inch radius like the one on this Eaton B-Line vertical outside bend is specified where big conductors or fiber run through the elevation change. The tradeoff is space: the fitting eats 51 inches of run. Smaller radius fittings are for control and instrumentation cable where the allowable bend is much tighter.

Aluminum is the usual choice for damp, coastal, and chemically aggressive environments because it forms a protective oxide rather than rusting through like painted steel, and this Eaton B-Line vertical outside bend is aluminum throughout. It is also non-magnetic and light to hang. Where it struggles is direct contact with strong alkalis such as wet concrete or lime, and with dissimilar metals, so isolate the splices and supports accordingly.

What you are ordering is the bend fitting itself, model 6A-24-90VO48. Splice plates, hardware, and hangers are separate line items, and a 90 degree vertical outside bend needs a connection set at each end plus support close to the fitting on both sides of the elevation change. Order splice kits matched to the Series 2-5 aluminum tray so you are not mixing steel hardware against aluminum rail.

The fitting weighs 24.3 lb, which is light for its size because it is aluminum rather than steel. One person can handle it on the ground; at height, with 51 inches of length and a 24 inch width to control, it is a two-man lift onto the hangers.

It carries a CE marking. That is the marking stated for the 6A-24-90VO48 vertical outside bend; if your project specification calls out a particular North American listing or load class, confirm that against the series load data before submittal.
