B-Line Eaton series wireway telescoping fitting, Lay-in, Wireway telescoping fitting, 1, Galvanized steel, 2.5" X 2.5"

The Eaton B-Line 22 FTFGV telescoping fitting is built for 2.5 inch by 2.5 inch wireway, the small square trough size used for control and branch circuit runs. It will not mate with 4x4 or 6x6 trough, so match the fitting to the cross section of the run you are joining.

No. This fitting is NEMA 1 rated, which is indoor general purpose only. It gives a degree of protection against incidental contact and falling dirt, not against water, dust, or oil. For outdoor, damp, or washdown locations you need a NEMA 3R or NEMA 4 rated wireway and matching fittings.

A telescoping fitting closes a gap between two fixed sections of wireway that cannot be moved to meet. You use it on the last piece of a run, between two boxes or panels already set, where an exact cut length is not practical. It slips over the adjacent trough and adjusts to take up the difference rather than forcing you to fabricate a filler. If both ends of your run are still free to move, a straight coupling section is the simpler choice.

Yes, the 22 FTFGV telescoping fitting is UL Listed, which is what an electrical inspector will look for on a wireway run in a commercial or institutional building.

Lay-in. The 22 FTFGV uses a removable cover so conductors drop into the trough rather than being pulled through a closed raceway, which is the reason most installers pick wireway over conduit for dense panel-feed work in the first place.

Galvanized steel. The zinc coating handles the humidity swings of an unheated indoor space like a warehouse or shop better than painted steel, but the fitting is still a NEMA 1 indoor product. An open parking garage or anywhere exposed to weather calls for a raintight rated wireway system instead.
