B-LINE 4A-24-30-HT24 – Frequently Asked Questions
1) What tray widths does the B-Line 4A-24-30-HT24 horizontal tee connect?
It is an expanding tee, so it joins two different tray widths: 24 inch and 30 inch. That is what the "expanding" in the name means, and it is why you would pick this fitting instead of a straight 24 inch tee when a 30 inch run branches off a 24 inch main.
2) What bend radius does this cable tray tee have, and does it suit large power cable?
The fitting is made on a 24 inch radius. That radius is what governs the minimum bending radius of the cable turning through the tee, so if your cable manufacturer calls for a bend radius at or under 24 inches you are inside the fitting's geometry. For cable requiring more, you need a larger radius fitting.
3) What does the 30 degree angle on this B-Line expanding tee mean?
The branch leaves the main run at 30 degrees rather than a square 90. That gives a swept takeoff instead of a right angle turn, which is easier on cable pulling tension, but it also means your branch run has to be laid out on that 30 degree line, not perpendicular to the main.
4) Should I use an expanding tee or a straight tee plus a reducer on my cable tray run?
If the branch is a different width than the main, the expanding tee does both jobs in one fitting, here taking 24 inch to 30 inch in a single 39 inch long piece. A straight tee plus a separate reducer adds a joint, more splice plates and more length in the ceiling. Use a straight tee only when the branch is the same width as the main.
5) What part number do I order for the 24 to 30 inch horizontal aluminum tee?
Order Eaton B-Line 4A-24-30-HT24. That single part number covers the 4 inch aluminum series 2-5 horizontal expanding tee with the 24 inch radius, 30 degree branch.
6) How much does this 24 to 30 inch cable tray tee weigh for rigging and hanger spacing?
30.03 lb bare, before any cable load. Because it is aluminum rather than steel, one or two people can set it, but the branch point still wants a hanger close to each leg since the fitting plus fill concentrates weight at the intersection.
7) Why choose aluminum cable tray fittings over steel for this kind of branch?
Aluminum, which this tee is made from, is lighter to handle overhead and holds up in damp or corrosive environments without galvanizing. Steel is the choice where you need higher load capacity per span. Keep the whole run in one material, aluminum fittings into a steel tray creates a dissimilar metal joint at the splice.
