B-LINE 4A-18-42-HT12 – Frequently Asked Questions

1) What tray widths does the B-Line 4A-18-42-HT12 horizontal tee connect?
The Eaton B-Line 4A-18-42-HT12 is an expanding horizontal tee: it joins an 18 inch wide tray run to a 42 inch wide branch. That is what the "expanding" designation means, so it does double duty as a tee and a width transition. If both your runs are the same width, you want a straight (non-expanding) horizontal tee instead.
2) How much room do I need to leave in the ceiling for this expanding tee?
Plan for a fitting that measures 24 inches in length/depth, 18 inches in width, and 4 inches in height, with a 12 inch radius turn. Allow clearance on the branch side for the 42 inch tray it opens out to, plus room to get a wrench on the splice plates at each of the three connection points.
3) Is this cable tray tee aluminum or steel, and how heavy is it to rig?
Aluminum, weighing 33.954 lb. That is a two-man lift on a lift or scaffold at height, but far lighter than the steel equivalent, and it will not rust in damp mechanical rooms or outdoor runs. Aluminum also means you need to keep your bonding jumper program consistent across the run.
4) Does this Eaton B-Line cable tray fitting carry a CSA listing for Canadian jobs?
It is CSA certified, which is what an inspector on a Canadian project will look for on tray and tray fittings.
5) Do splice plates come with the B-Line 4A-18-42-HT12 tee?
Order splice plates and hardware separately. The 4A-18-42-HT12 ships as the expanding tee fitting itself, and it has three connection points to make up: the two 18 inch straight-run ends and the 42 inch branch. Size the splice hardware to match your Series 2-5 aluminum tray.
