B-LINE 4A-12-36-HT12 – Frequently Asked Questions
1) What tray widths does the B-Line 4A-12-36-HT12 expanding tee connect?
Model 4A-12-36-HT12 is an expanding horizontal tee built for 12 inch and 36 inch tray widths, so it takes a 12 inch run into a 36 inch branch (or the reverse) in one fitting instead of needing a separate reducer plus a straight tee.
2) How much room do I need to lay out for this tee in the ceiling space?
Plan on 21 inches of length and 12 inches of width for the fitting body, with a 4 inch side rail depth. Drop that footprint into your coordination drawing before you set hangers, since the 12 inch radius turn pushes the branch out further than a square tee would.
3) Is this cable tray tee aluminum or steel?
Aluminum. That keeps the fitting light for overhead work at 18.305 lb and suits it to the same runs as aluminum Series 2-5 tray. Mixing it into a galvanized steel run is a dissimilar metal decision you should make deliberately.
4) Is a horizontal expanding tee the right fitting, or should I use a straight tee and a reducer?
Use the expanding tee when the branch leaves the run at a different width, here 12 inch to 36 inch, and both stay in the same horizontal plane. A straight tee assumes both legs are the same width and would need a separate reducer section added, which adds joints and length to the run. If the branch drops or rises out of plane, neither one works; that calls for a vertical fitting.
5) Can one electrician set this tee by hand?
At 18.305 lb it is a one-person lift, but positioning a 21 inch long fitting on a lift or ladder while landing splice plates on both widths is usually a two-person job.
6) Does this Eaton B-Line tee carry any marking for a European spec job?
It is CE marked, which is what a spec calling for European conformity is looking for on the fitting.
