B-Line Eaton series imperial cable tray and ladder, 4" Height, 51" Length, 24" Width, 24" and 6" Tray widths, Series 2-5 horizontal reducing tee, Alum

Model 4A-24-06-HT36 is a horizontal reducing tee that joins a 24 inch wide run to a 6 inch wide branch. The run side matches 24 inch tray and the reduced outlet takes 6 inch tray, so you don't need a separate reducer plate between the tee and the smaller branch.

Plan for 51 inches of overall length and 24 inches of width in the fitting itself, with a 36 inch bend radius on the turn. The 36 inch radius is the largest of the common tray radii, so it is the choice when you have large-diameter power cable and need to respect minimum bend radius on the conductors. Check your ceiling or rack space before ordering, because a 51 inch fitting needs more clear run than a 12 or 24 inch radius tee.

It is aluminum. Aluminum tray fittings are the usual pick outdoors, in damp areas, and in corrosive or coastal environments where painted steel would need coating maintenance, and the lighter weight helps on long overhead supported runs. At 30.75 lb for this fitting, two people can still set it without a lift. If your run is already galvanized steel tray, match steel instead so the splice plates and bolt holes line up and you avoid dissimilar metal contact.

It carries CSA certification, so it is acceptable for jobs in Canada that call for a certified cable tray fitting. That matters for institutional and industrial specs where the inspector wants a certification mark on every tray component, not just the straight sections.

Order Eaton B-Line part number 4A-24-06-HT36. Reading the number: 4 inch depth aluminum, 24 inch main width, 6 inch branch width, horizontal tee, 36 inch radius. Distributors cross-referencing should keep the HT36 suffix, since the same 24 to 6 reducing tee also exists in other radii.

The 4A-24-06-HT36 is supplied as the fitting itself. Splice plates, hardware, and hangers or trapeze supports for the three legs are separate items, so add them to the order. Note that a 51 inch fitting with a 36 inch radius needs support on both sides of the turn, not just at the main run splice.
