B-LINE 4A-18-36-HT12 – Frequently Asked Questions
1) What tray widths does the B-Line 4A-18-36-HT12 expanding tee connect?
The 4A-18-36-HT12 is a horizontal expanding tee built to join an 18 inch wide run to a 36 inch wide run. That is what "expanding" means here: the branch and the through-run are not the same width, so you do not need a separate reducer fitting between them. Its own listed width is 18 inches with a 24 inch length.
2) What bend radius is the 12 in the B-Line 4A-18-36-HT12 part number?
It is the inside radius of the fitting: 12 inches. That radius controls how tightly the cable can turn through the tee, so it has to be at least the minimum bend radius of the largest conductor in the tray. If your cable calls for a 24 or 36 inch radius, this fitting is the wrong one.
3) Is this B-Line cable tray tee UL listed for an inspected commercial job?
The 4A-18-36-HT12 expanding tee is UL Classified. That is the classification electrical inspectors look for on cable tray fittings used as part of a listed tray system.
4) Do splice plates and hardware come with the B-Line expanding tee?
The 4A-18-36-HT12 is sold as the tee fitting itself. Splice connectors and their bolts are ordered separately and must match the series and material of your run, so add aluminum splice plates for Series 2-5 tray at each of the three connection points.
5) Horizontal tee or a reducer plus a standard tee for branching an 18 inch run off a 36 inch tray?
One expanding tee does the job of both. The 4A-18-36-HT12 takes the width change from 18 to 36 inches inside the fitting, so you lose no straight length to a separate reducer and you have two fewer splice joints to make. Use a same-width tee only when both the run and the branch are the same tray width.
6) Is this a horizontal or a vertical cable tray tee?
Horizontal. The 4A-18-36-HT12 branches in the flat plane, for a tee where all three legs stay at the same elevation. Changing levels requires a vertical inside or outside bend instead.
7) How heavy is this 18 by 36 inch cable tray tee for overhead rigging?
It weighs 19.71 lb. Light enough for two people to set on trapeze hangers by hand, but plan support on both the 18 inch and 36 inch sides of the fitting rather than cantilevering it off one run.
