B-LINE 66 FTF – Frequently Asked Questions
1) What is a telescoping fitting used for in a wireway run?
It closes a gap between two fixed sections of 6x6 wireway that cannot be moved, for example between two mounted enclosures or where a run is cut short in the field. The body slides to take up the difference, so you don't have to cut and re-fab a full section. Lay-in construction means the cover comes off and conductors drop in rather than being pulled.
2) Is the 66 FTF wireway fitting rated for outdoor or wet locations?
No. It is a NEMA 1 enclosure rating, which is indoor, dry-location, general-purpose protection against incidental contact and falling dirt. For outdoor or washdown work you need a NEMA 3R or 4 raintight wireway fitting instead.
3) Is the Eaton B-Line 66 FTF UL Listed?
Yes, the 66 FTF telescoping fitting is UL Listed, which is what most inspectors and institutional specs look for on a NEMA 1 steel wireway system.
4) How much room do I need to allow for the 66 FTF telescoping fitting?
Overall it measures 12 in length/depth, 8.75 in wide and 6.25 in high, so plan roughly a foot of run for the fitting body with clearance for the overlap and cover removal. It weighs 5.173 lb, light enough for one person to set in place on a supported run.
5) How do I order the right B-Line telescoping fitting, and what is the part number?
Order by catalog number 66 FTF for the 6x6 NEMA 1 steel lay-in version in ANSI 61 gray. The first two digits are the wireway cross section, so match them to the trough you are tying into.
6) What finish does the B-Line 66 FTF come in, and will it match existing wireway?
It is painted ANSI 61 gray over steel, the standard gray used across Eaton B-Line wireway and most switchgear, so it blends with an existing B-Line run and with typical panel and gutter finishes in a mechanical room.
