B-Line Eaton series wireway tee fitting, Lay-in, Tee fitting, 1, Steel, ANSI 61 gray painted finish, 8" X 8"

Yes. The Eaton B-Line 88 T is sized for 8 inch by 8 inch lay-in wireway, with 8 inch height and 8 inch width on the fitting body and a 16 inch overall length/depth. It joins three runs of 8 x 8 trough at a tee. If your run is 4 x 4 or 6 x 6, this fitting will not bolt up; you need the tee sized to that cross section.

No. The 88 T is a NEMA 1 fitting, which is indoor, general purpose enclosure protection only. It keeps fingers and falling dirt out, not water. For an exterior wall, a wash-down area, or anywhere subject to rain or hose spray, use a NEMA 3R or NEMA 4 raintight wireway fitting instead.

Lay-in means the cover comes off along the length of the fitting so conductors drop straight into the trough instead of being pulled through. On a tee that matters a lot: you can lay cable into all three legs and dress the turn by hand rather than fishing a 90 at a junction. It is the reason electricians run wireway instead of conduit on dense panel feeds and control rooms.

Yes, the Eaton B-Line 88 T carries a UL Listing. That is usually what an inspector or a spec writer on an institutional job is looking for on the wireway system components, and it is stated on the fitting itself, not just the trough.

The manufacturer part number is 88 T, from the Eaton B-Line wireway series. The first two digits reference the 8 inch by 8 inch cross section and T designates the tee fitting.

It is steel with an ANSI 61 gray painted finish, the standard gray used across Eaton B-Line wireway, panelboards, and most industrial control enclosures. So a tee dropped into an existing ANSI 61 gray run will match visually without field painting.

The 88 T weighs 10.226 lb empty. Add conductor weight in all three legs and the trapeze or strut support at the tee is carrying noticeably more than a straight length, so plan hanger spacing and anchors at the fitting accordingly.
