B-Line Eaton series imperial cable tray and ladder, 6" Height, 39.062" Length, 36" Width, Series 2-5 vertical outside bend, Aluminum, 45° Angle, 48" R

A vertical outside bend carries the tray run up and over an obstruction or a change in elevation, bending away from the cable side so the cables ride on the outside of the curve. This Eaton B-Line fitting, model 6A-36-45VO48, turns the run 45 degrees on a 48 inch radius. The generous radius is what keeps the cable bend within limits on a direction change, which is why these fittings are sized by radius rather than just angle.

It depends which way the tray turns relative to the cable. Use an outside bend when the run changes elevation such that the cables lie on the outer, convex face of the curve, for example where a horizontal run rises to clear a beam. If the cables would sit on the inner, concave side of the turn, you want a vertical inside bend of the same width and radius instead. Ordering the wrong one leaves you with a fitting that will not follow your elevation change.

Allow for a fitting that runs 39.062 inches along its length. Between that and the 48 inch radius, a 45 degree elevation change eats several feet of horizontal run, so lay it out before you cut your straight sections. If headroom or wall clearance is tight, a smaller radius fitting is the way to shorten the transition.

Substantially. This 36 inch wide bend weighs 14.9 lb, which is a one-man lift on a lift or scaffold even at that width. Aluminum is also the usual pick for corrosion resistance in wet, coastal or chemical environments, where galvanized steel would need extra coating.

The order covers the 45 degree vertical outside bend itself. Splice plates, bolts and any hangers or supports for the fitting are separate items, so add the B-Line splice hardware matched to your Series 2-5 aluminum tray when you order.

Order Eaton B-Line part 6A-36-45VO48. Read the number straight off: 6 inch rail, aluminum, 36 inch width, 45 degree vertical outside bend, 48 inch radius. Change any of those and the suffix changes too, so quote the full number on a purchase order.

It is CE marked. No other rating is carried on this fitting, so if your specification calls out a particular tray load class or listing, confirm it against the straight section series you are building the run from.
