B-Line Eaton series imperial cable tray and ladder, 6" Height, 23.63" Length, 36" Width, 36" and 9" Tray widths, Series 2-5 right reducer, Aluminum

It transitions a 36 inch wide aluminum cable tray down to a 9 inch wide tray, with the reduction taken off to the right side. The straight side stays in line, so the run keeps one continuous edge while the tray narrows. Model 6A-36-RR09 is a Series 2-5 right reducer with a 6 inch side rail height and 23.63 inch length.

Reducers are handed, and picking the wrong hand means the narrow tray lands on the wrong side of the run. The 6A-36-RR09 is a right reducer: face the direction of the reduction and the offset is taken on the right, leaving the left rail straight. If your narrowed tray needs to stay flush on the other side, you want the left version instead. If it needs to center, that is a straight reducer, not this part.

It is built with a 6 inch side rail height in aluminum, so it lines up rail-for-rail with 6 inch deep aluminum tray in the same Series 2-5 family. Match on three things: rail height (6 inch), material (aluminum, so you are not bolting aluminum to steel and creating a dissimilar-metal joint), and the two widths at each end, 36 inch and 9 inch.

Allow 23.63 inches of straight run length for the reducer section itself, measured along the tray. That is the fitting length only, so add your splice plate laps and keep a support point within the manufacturer's spacing on each side of the transition. Overall footprint at the wide end is 36 inches across.

Aluminum is the choice where weight and corrosion matter: this reducer weighs 8.5 lb, which one electrician can set and hold while splicing overhead, and aluminum holds up in damp and coastal environments without galvanizing. Steel tray is the call where you need higher load capacity per span or where the spec calls for it. Do not mix the two at a splice without isolating the joint.

Order Eaton B-Line 6A-36-RR09. The number reads as 6 inch rail height, aluminum, 36 inch wide inlet, right reducer to 9 inch. One model covers this configuration, so there is no finish or length option to specify on top of it.

The fitting weighs 8.5 lb bare. Add that to the cable fill weight across the 23.63 inch transition when you size the trapeze or hanger rod at the support nearest the reducer. It is light enough to handle by hand on a lift, which is the practical advantage of the aluminum section over a steel equivalent.

It carries CE marking. That is the certification held on record for the 6A-36-RR09 aluminum right reducer, and it is what you can reference on a submittal for this fitting.
