B-Line Eaton series imperial cable tray and ladder, 6" Height, 60" Length, 18" Width, Series 2-5 horizontal tee, Aluminum, 48" Radius

The 6A-18-HT48 is built for 18 inch wide, 6 inch deep Series 2-5 aluminum tray. Width and rail depth have to match the straight sections it ties into, so this one drops in on an 18 inch run with 6 inch side rails. On a different tray width you need the tee sized to that width instead.

It is a 48 inch radius fitting. That is the largest of the common tray fitting radii, and it is what you specify when the cable you are pulling has a large minimum bend radius, typically heavy power feeders or large fiber bundles. If your cable allows a tighter turn, a 12, 24 or 36 inch radius tee takes up far less overhead space.

This tee is aluminum, which is the usual pick for outdoor, damp and lightly corrosive environments because it does not need galvanizing to resist rust, and it is roughly a third the weight of a comparable steel fitting. For heavy chemical exposure or where the spec calls for steel throughout, match the tray material rather than mixing aluminum fittings into a steel run.

Eaton B-Line part number 6A-18-HT48. Reading the code: 6 inch rail, aluminum, 18 inch width, horizontal tee, 48 inch radius. If you need a different width or radius on the same Series 2-5 tray, the same pattern applies with those numbers swapped.

Treat splice plates and connection hardware as a separate line. The record for the 6A-18-HT48 covers the tee fitting itself, sized at 18 inches wide with 6 inch rails, and each of the three legs needs a splice connection to the adjoining straight section. Order the splice kits matched to your Series 2-5 aluminum tray.

It is CE marked. Nothing further is listed on the record for it.
