B-LINE 4A-36-LR18 – Frequently Asked Questions

1) What does a left reducer do on a cable tray run, and when do I need one?
A left reducer is the transition fitting you use when a cable tray run steps down from one width to a narrower one. The Eaton B-Line 4A-36-LR18 takes a 36 inch wide tray down to an 18 inch wide tray, with the offset taken on the left side so one side rail stays in a straight line. Use it where the cable fill drops off partway along a run and you no longer need the full 36 inch width. If you want the reduction centered or taken on the right instead, that is a different fitting.
2) How do I tell whether I need a left reducer or a right reducer?
Stand at the wide end and look down the run in the direction the tray is reducing. A left reducer keeps the right side rail straight and brings the left rail in. Getting this backwards leaves the run offset the wrong way against your wall or support steel, so confirm the direction of travel before ordering the 4A-36-LR18.
3) Is the B-Line 4A-36-LR18 cable tray reducer aluminum or steel?
Aluminum. That keeps the weight down at 4.6 pounds for a fitting of this size, which one person can set and bolt up on a ladder without a second hand. Aluminum is also the usual choice where the run is outdoors or in a damp or corrosive area rather than a dry indoor plant.
4) Does this Eaton B-Line cable tray reducer carry any certification for a Canadian job?
The 4A-36-LR18 reducer is CSA certified, which is what an inspector on a Canadian project will be looking for on cable tray components.
5) How much length does the 36 to 18 inch reducer add to my tray run?
Budget 18.44 inches of run length for the fitting itself. That is the dimension to work into your support spacing and your straight section takeoff when you lay the run out, since the reduction is not made at a single joint.
6) What part number do I order for a B-Line 36 to 18 inch left-hand tray reducer in aluminum?
Order Eaton B-Line model 4A-36-LR18. The designation reads across as 4 inch height, aluminum, 36 inch wide end, left reducer to 18 inches.
