Bridgeport Fittings BF-191 – Frequently Asked Questions

1) What does a Bridgeport Lock-A-Liner actually do on a metal bushing?
It snaps into an ordinary bushing or connector and lines the throat with insulating polypropylene, turning that fitting into a code-approved insulated bushing or connector. That is the whole point of the part: instead of pulling the metal fitting and replacing it with an insulated-throat version, you add the liner. It carries a NEMA FB-1 rating and is UL listed under file E11259.
2) What trade sizes do Bridgeport Lock-A-Liners come in?
Six sizes, matched to conduit trade size: 1/2 inch (191), 3/4 inch (192), 1 inch (193), 1-1/4 inch (194), 1-1/2 inch (195) and 2 inch (196). Order the liner to the trade size of the bushing or connector it is going into, not to the wire size.
3) Inspector flagged my conduit terminations for missing insulated throats. Can I fix that without redoing the fittings?
That is the retrofit this part exists for. Adding a Lock-A-Liner to the existing bushing or connector converts it to a code-approved insulating bushing or connector, so the metal fitting and the conduit stay in place. It is UL listed under file E11259 and rated NEMA FB-1, which is the standard that covers insulating bushings, so the corrected termination is documentable.
4) Will a plastic liner hold up at panel and gutter temperatures?
The polypropylene liner lock construction is heat rated to 150 C, so it is intended for high-temperature electrical enclosures and raceway terminations rather than just cool interior work. Material is plastic, colored black with a plain finish.
5) Are Bridgeport Lock-A-Liners acceptable for commercial and industrial inspection, or residential only?
They are used across commercial electrical installations, industrial facility upgrades, residential service panel work, and code compliance retrofits. All Bridgeport fittings meet OSHA-recognized, NRTL-listed electrical standards, and this liner carries UL file E11259 plus a NEMA FB-1 rating.
6) Where are Bridgeport Lock-A-Liners made? I have a domestic-sourcing requirement on the job.
Country of origin is the United States, which is what public and institutional buyers with domestic preference clauses need on record.
7) I need to stock these for an MRO crib. What is the part numbering so I can standardize?
The numbering runs straight up with trade size: 191 is 1/2 inch, 192 is 3/4 inch, 193 is 1 inch, 194 is 1-1/4 inch, 195 is 1-1/2 inch, 196 is 2 inch. Same black polypropylene liner across all six, so one bin per size covers most bushing and connector terminations a maintenance crew touches.
