B-LINE 4A-18-30-HT12 – Frequently Asked Questions
1) What does the B-Line 4A-18-30-HT12 horizontal tee actually do in a cable tray run?
It is a Series 2-5 horizontal expanding tee, so it branches a run flat (in the horizontal plane) and changes tray width across the fitting. The 30 degree angle applies to the branch, and the fitting turns on a 12 inch radius, which is what sets the bend the cable takes through the junction.
2) What tray widths does this B-Line expanding tee connect?
It is built for 18 inch and 30 inch tray widths, which is why it is called an expanding tee: the main run and the branch are not the same width. The fitting itself is catalogued at 18 inches wide. If both of your tray runs are the same width, you want a straight (non-expanding) tee instead.
3) How much room do I need to lay out for the 4A-18-30-HT12 tee?
Allow 24 inches of length for the fitting, 18 inches of width, and 4 inches of depth. With a 12 inch radius on the turn, plan the branch takeoff so the cable bend is not fighting a wall or a structural member right at the tee.
4) Is this cable tray tee aluminum or steel, and does that matter for my environment?
Aluminum. That keeps the piece light for overhead work and is the usual choice where a galvanized steel tray would be a corrosion risk. Match the fitting material to the rest of the run so you are not mixing aluminum and steel at a bolted splice.
5) What part number do I order for this 18 to 30 inch expanding tee?
Order Eaton B-Line part 4A-18-30-HT12. The number reads out the configuration: 4 inch aluminum, 18 to 30 inch widths, horizontal tee, 12 inch radius.
6) How heavy is the B-Line 4A-18-30-HT12 tee for a single-person overhead install?
18.23 lb. That is a one-man lift on a ladder, but at 24 inches long and 18 inches wide it is awkward enough that a second set of hands helps while you land the splice plates.
7) Does this B-Line cable tray fitting carry any listings for a spec submittal?
It carries a CE marking. That is the certification held on record for this Series 2-5 expanding tee.
