B-Line Eaton series imperial cable tray and ladder, 6" Height, 45.188" Length, 18" Width, Series 2-5 vertical inside bend, Aluminum, 90° Angle, 36" Ra

Yes, that is exactly what it's built for. The 6A-18-90VI36 is a 90 degree vertical inside bend sized for 18 inch wide tray with a 6 inch side rail height, in aluminum, so it matches an aluminum Series 2 through 5 ladder run of the same width and depth. The bend turns 36 inch radius and measures 45.188 inches overall in length.

Direction of the turn relative to the cable. A vertical inside bend, which is what the 6A-18-90VI36 is, turns the tray so the cables run along the inside of the curve, the bend you use when the tray drops down or rises with the load bearing toward the concave side. A vertical outside bend curves the other way. Get the two mixed up and the bend won't line up with the run at the transition point, so confirm which way your tray changes elevation before ordering. This one turns a full 90 degrees on a 36 inch radius.

It matters a lot. The 36 inch radius on this bend sets the minimum bending radius your conductors see through the elevation change. Large power and medium voltage cable often carries a manufacturer minimum bend radius that a short radius fitting will violate, which is why B-Line offers bends in several radii. If your cable schedule calls for a tighter radius than 36 inches you can use a shorter radius fitting, but you cannot go the other direction, a 36 inch radius fitting will not satisfy a spec calling for larger.

Aluminum. That makes the 6A-18-90VI36 a good match for damp, coastal, or chemically aggressive environments where plated or painted steel tray would need coating maintenance, and it keeps the piece light for overhead work at 20.6 lb. Keep the whole run in one material family, mixing an aluminum fitting into a steel tray run creates a dissimilar metal contact at the splice.

Eaton B-Line part number 6A-18-90VI36. Reading the code: 6 inch rail height, aluminum, 18 inch width, 90 degree vertical inside bend, 36 inch radius. Quote that number and the width, depth, and radius all come along with it.

The 6A-18-90VI36 ships as the bend itself. Splice plates, hardware, and hanger or trapeze support are ordered separately, and each end of the fitting needs a splice connection to the adjoining straight sections, so plan on two sets of splice plates plus support within the spacing your tray run uses.

20.6 lb. Light enough for one electrician to set on trapeze hangers, though at 45.188 inches long through the curve it's an awkward carry up a ladder and easier handled by two.

It is CE marked. That's the certification held on record for the 6A-18-90VI36 vertical inside bend, which matters if the job or the equipment package is bound for a CE jurisdiction.
