B-Line Eaton series wireway telescoping fitting, Lay-in, Wireway telescoping fitting, 1, Steel, ANSI 61 gray painted, 12" X 12"

A telescoping fitting is the adjustable closure piece used to join two lengths of wireway when the gap between them is not an even trough length, or when the run has to be made up between two fixed pieces of equipment. It slips over the adjoining wireway ends and takes up the difference, so you do not have to cut and refab a trough. The Eaton B-Line 1212 FTF is sized for 12 inch by 12 inch wireway and is a lay-in type, meaning conductors drop in from the open side rather than being pulled through.

It is built for 12 inch by 12 inch trough. The fitting itself measures 12 in length/depth, 12.25 in height and 12.37 in width, so the body laps over a 12x12 cross section. It will not serve a 4x4, 6x6 or 8x8 run, and it will not adapt one size to another. Match the fitting size to the trough size on both sides of the joint.

No. The 1212 FTF is a NEMA 1 enclosure rating, which is indoor, general purpose, dust and falling dirt only. It gives no protection against rain, sprinkler discharge, washdown or hosing. For a loading dock, rooftop, exterior wall or any wet location you need a NEMA 3R raintight wireway and raintight fittings instead.

Yes, it is UL Listed. That matters when the wireway run is part of a permitted installation and the inspector wants listed components throughout, fittings included.

Use a plain coupler when two trough ends butt together cleanly at a fixed length. Use a telescoping fitting like the 1212 FTF when the remaining gap is an odd dimension, when you are tying into equipment already set in place, or when you need a little slack to get the last section in. The telescoping body slides to take up the difference; a coupler gives you no adjustment at all.

Yes. This fitting is a lay-in design, so the cover comes off and conductors are laid into the open channel instead of being fished through. That is the main labor advantage of 12x12 wireway on large feeder and control work, and the fitting keeps that same lay-in access at the joint.

Order Eaton B-Line part number 1212 FTF. That is the 12 inch by 12 inch NEMA 1 lay-in telescoping fitting in ANSI 61 gray painted steel.

Steel with an ANSI 61 gray painted finish, which is the standard gray used across B-Line wireway and most electrical enclosures, so it blends with an existing ANSI 61 run. If your trough is a different color or a galvanized/stainless run, the fitting will not match visually even though it mates dimensionally.

About 10.475 lb. It is painted steel, so on an overhead 12x12 run figure the fitting weight plus conductor fill when you space hangers and trapeze supports at the joint.
