B-Line Eaton series imperial cable tray and ladder, 6" Height, 20.692" Length, 18" Width, Series 2-5 vertical inside bend, Aluminum, 30° Angle, 24" Ra

A vertical inside bend carries the tray run up or down while the fitting curves toward the inside of the angle, so the cables stay in the tray bed as elevation changes. The B-Line 6A-18-30VI24 is a 30 degree vertical inside bend for Series 2-5 aluminum ladder tray, 18 inches wide with 6 inch side rails and a 24 inch radius. Use it where a run has to drop under an obstruction or climb a wall at a 30 degree pitch rather than a square 90.

It depends which way the run turns relative to the tray bed. An inside bend curves toward the cable side, used when the run rises away from the fitting, such as a run climbing a wall off a horizontal ceiling run. An outside bend curves the other way, used when the run drops over an edge. Ordering the wrong one is the most common mistake on an elevation change, and the two are not interchangeable. This part is the 30 degree inside version for 18 inch wide Series 2-5 aluminum tray.

Allow for a fitting that runs 20.692 inches along its length, measured as supplied, with the 24 inch inside radius driving the curve. Lay that out on the elevation change before you cut the straight sections, since a 24 inch radius fitting takes noticeably more run than a short radius one. The bend itself weighs 5.6 pounds, so it is a one-man lift into a support.

The 6A-18-30VI24 bend carries CSA certification, which is what inspectors in Canadian jurisdictions look for on cable tray and its fittings.

Order it as B-Line 6A-18-30VI24. The number reads out as it builds: 6 inch rail, aluminum, 18 inch width, 30 degree vertical inside, 24 inch radius. Splice plates and hardware to join it to the adjacent straight sections are separate line items.

This fitting is aluminum, which is the usual call where weight matters and where a damp or mildly corrosive environment would attack painted steel. It also keeps the run light for overhead trapeze supports at 5.6 pounds for the bend. Where you need maximum load capacity over long support spans, a steel Series tray is the alternative, but do not mix the two in one run without addressing the dissimilar metal contact.
