B-Line Eaton series imperial cable tray and ladder, 4" Height, 18.44" Length, 24" Width, 24" and 6" Tray widths, Series 2-5 left reducer, Aluminum

It is a transition fitting that steps a 24 inch wide aluminum tray run down to a 6 inch wide tray. The reduction is taken on the left side, so the right side rail stays in line with the existing run and the left rail angles in. Model 4A-24-LR06, 4 inch tray height, 18.44 inches long.

Reducers are handed, so this one is not interchangeable with a right version. Stand facing the direction of the cable run and look at which side rail has to move inward to get from 24 inches down to 6 inches. If the offset is on the left, the 4A-24-LR06 is the piece. If the run holds its left rail straight and the right rail comes in, you need the right-hand equivalent. Straight (centered) reducers exist too, where both rails come in evenly.

Aluminum is what this reducer is made from, and at 4.9 lb for an 18.44 inch fitting it is light enough to handle overhead on a ladder without a second man. Aluminum suits corrosive and wet indoor or outdoor environments and needs no galvanizing. Steel tray is the alternative where you need higher load capacity per span or where the spec calls for it. Do not mix the two in direct contact in a damp location.

Allow 18.44 inches of straight length for the fitting itself, plus room for splice plates at both ends. That 18.44 inches is the transition zone where the left rail angles inward, so do not plan a support hanger or a wall penetration inside it.

What ships is the reducer section itself, model 4A-24-LR06 in aluminum, weighing 4.9 lb. Splice plates, bolts, and any hangers or trapeze supports are ordered separately, so count the connections at both ends when you build the order.

Yes, it works in either direction of the run. It is the same fitting whether the cable pulls from the wide end to the narrow or the reverse; what matters is that the offset falls on the left side and that both trays are 4 inch deep aluminum of the same series.
