Bridgeport Fittings 571-S – Frequently Asked Questions

1) What conduit sizes do the Bridgeport 571-S and 572-S strap connectors cover?
Two sizes are offered: the 571-S for 1/2 inch flexible metal conduit and the 572-S for 3/4 inch. Both are the standard throat version. Match the number to the trade size of the flex you are terminating, not to the knockout in the box.
2) Can I use these flex connectors in a damp or corrosive area like a parking garage or mechanical room?
The zinc electroplated finish on these steel strap connectors is there for corrosion resistance in harsh environments, which is the usual reason contractors pick a zinc-plated steel strap over a plain one. They are not liquidtight fittings, though. For a wet location or where a liquidtight seal is required, go to a liquidtight connector such as the RACO 4734 SWIVEL-LOK Type B liquidtight connector.
3) Are Bridgeport strap connectors UL listed for inspection sign-off?
Yes. The strap connectors are UL listed under UL File E20534 and are RoHS compliant, which is what an inspector or a spec reviewer on a commercial job will be looking for.
4) I need a flexible metal conduit connector for 1 inch FMC - the Bridgeport 571-S and 572-S only go up to 3/4 inch. What else works?
The Bridgeport U-shaped strap connectors are offered in 1/2 inch (571-S) and 3/4 inch (572-S), so a 1 inch flex run needs a different fitting. The Thomas & Betts 306 is a straight Tite-Bite connector sized as a 1 inch FMC fitting and is non-insulated. Note the difference in how the conduit is retained: the Bridgeport connectors use a U-shaped strap that you tighten with a single screw after inserting the conduit, while the Tite-Bite is a straight connector of a different retention style, so field technique and throat appearance will not match a 571-S or 572-S on the same enclosure.
5) Can I use a Bridgeport 571-S strap connector on liquidtight flexible conduit in a wet or washdown area?
No. The Bridgeport U-shaped strap connectors are built for steel or aluminum flexible metal conduit terminating into a box or enclosure, and they do not provide a liquidtight seal. For liquidtight flex, the RACO 4734 is a 1 inch Type B liquidtight connector in the SWIVEL-LOK series, made of nylon and multi-position so the fitting body can be angled after the conduit is set. The trade-off is material: the Bridgeport fitting is steel with a zinc electroplated finish for corrosion resistance in harsh environments, where the RACO 4734 is nylon.
6) Will a Bridgeport U-shaped strap connector work with aluminum flex, or only steel?
Both. The strap connector is made to terminate steel or aluminum flexible metal conduit into a box or enclosure. The connector body itself is zinc electroplated steel.
7) How does a U-shaped strap connector install compared to a squeeze-type FMC fitting?
Installation is single-screw: push the flex into the connector and tighten one screw to clamp it. That is one fastener per termination instead of the two-screw squeeze clamp arrangement, which is why crews use straps on high-count flex work like fixture whips and motor drops. A snap-in or bite-type fitting such as the Thomas & Betts 306 Tite-Bite is the alternative when you want no screws at all, though that one is a 1 inch fitting.
8) Are these Bridgeport connectors insulated throat?
No. Both the 571-S and 572-S are the standard throat version. If your job spec calls for an insulated throat to protect conductor insulation at the box, specify an insulated-throat flex connector instead.
9) Is a 3M SC0001 stem connector an alternative to a Bridgeport 572-S?
No - they are unrelated parts despite both being called connectors. The 3M SC0001 is a stem connector rated up to 35 kV for 2 and 1 AWG conductors, so it joins conductors in a medium-voltage splice. The Bridgeport 572-S is a raceway fitting: a 3/4 inch U-shaped strap connector in zinc electroplated steel that terminates steel or aluminum flexible metal conduit into a box or enclosure. Ordering one in place of the other leaves the job with no usable part.
10) I need to standardize flex terminations across a building. Is the same connector used for both 1/2 and 3/4 inch flex?
Same design, two part numbers. Order 571-S for every 1/2 inch flex termination and 572-S for 3/4 inch. Finish and construction are identical across both (zinc electroplated steel), so the look and the corrosion behavior stay consistent across the facility.
