B-LINE 4A-12-24-HT12 – Frequently Asked Questions
1) What tray widths does the Eaton B-Line 4A-12-24-HT12 horizontal expanding tee connect?
The 4A-12-24-HT12 is a Series 2-5 horizontal expanding tee built for 12 inch and 24 inch tray widths. The expanding geometry is what lets the branch run leave at a different width than the through run, so you are not forced to keep one width across the whole intersection.
2) What bend radius is the B-Line 4A horizontal expanding tee made to, and does that matter for my cable?
It is a 12 inch radius fitting. That radius sets the minimum bending radius the cable sees as it turns through the intersection, so check it against the bend radius your cable manufacturer calls out, particularly for large power or fiber runs where a tighter turn is not allowed.
3) Is this B-Line cable tray tee aluminum or steel, and where can it be used?
Aluminum. It is lighter to hang and handle than a steel fitting of the same size, and aluminum is the usual choice where corrosion is a concern or where the support spacing benefits from less dead load. If your run is already galvanized or stainless steel tray, match the material rather than mixing at the intersection.
4) Should I use a horizontal tee or a horizontal cross at a cable tray branch?
Use the horizontal tee where one run branches off a straight run in three directions. A cross is the fitting when four legs meet at the intersection. This 4A-12-24-HT12 is the three-way tee, and because it is an expanding type it also handles the case where the branch is a different tray width than the main run.
5) Do splice plates or hardware come with the B-Line 4A-12-24-HT12 tee?
Order the fitting as the tee itself, model 4A-12-24-HT12. Splice plates and their bolt hardware are ordered separately in the B-Line series, and you will need a set at each of the three connection points where the tee joins straight tray.
6) How much does the B-Line 4A-12-24-HT12 tee weigh for lifting and support planning?
It weighs 13.757 lb. That is a one-person lift at grade, but on an overhead run you still want a support close to the fitting on each leg, since the tee adds concentrated load plus the weight of three cable runs converging.
7) Does this cable tray tee carry any certification marking?
It carries a CE marking. That is the only marking held on record for this fitting, so if your specification calls for a particular listing beyond CE, verify it against the submittal before release.
