B-Line Eaton series wireway telescoping fitting, Lay-in, Wireway telescoping fitting, 1, Galvanized steel finish, 8" X 8"

A telescoping fitting closes the gap between two sections of wireway when the run does not land on an even trough length, or when you need to pull a section out later without dismantling the whole run. The Eaton B-Line 88 FTFGV is the 8 x 8 inch size, so it mates to 8 by 8 inch wireway, and it is a lay-in design, meaning conductors drop in from the side rather than being fished through.

No. The 88 FTFGV telescoping fitting is NEMA 1, which is indoor, general purpose enclosure protection only. For a wet or outdoor run you need a NEMA 3R rated raintight wireway and matching fittings instead. The fitting is UL Listed.

The fitting measures 8.25 inches in height, 12.31 inches in width and 12 inches in length/depth, so it spans roughly a foot of run before telescoping is adjusted. Weight is 7.167 lb, so one electrician can set it without a lift.

The 88 FTFGV is galvanized steel, which handles dry indoor industrial spaces, warehouses and mechanical rooms fine. A covered but damp location such as an open parking deck is a different call: the enclosure rating here is NEMA 1, indoor general purpose, so a damp or exposed location calls for a raintight assembly rather than this one.

Order Eaton B-Line part number 88 FTFGV. That is the 8 x 8 inch, NEMA 1, galvanized, lay-in telescoping fitting. There is a single configuration, so no finish or size suffix to specify.

It is a lay-in fitting, so the body and its removable cover work together to let you drop conductors in from the side and close it up. What it does not include is the wireway itself or the connector hardware for the adjoining trough sections, those are ordered with the wireway.
