Bridgeport Fittings BF-642 – Frequently Asked Questions

1) Do I need a locknut to install a Bridgeport 642 clamp connector in a knockout?
No locknut needed. The Bridgeport two-piece clamp connectors are snap-in fittings that secure non-metallic cable to a box or enclosure without a locknut, so you can land them from outside the box without reaching inside to spin a nut on. That matters most in crowded panels and existing boxes full of conductors.
2) What size cable does the Bridgeport 642 connector clamp on?
The 642 takes cable in the .180 to .560 inch range. Step up to the 643 for .250 to .830 inch, and the 645 for .312 to 1.125 inch. Measure the flat or the diameter of the cable jacket, not the conductor, and pick the connector whose range brackets it. Cable outside the range will not clamp securely.
3) Are Bridgeport two-piece clamp connectors UL listed for inspection?
They are covered under UL File E11698 and carry the FB-1 NEMA rating for fittings and boxes. Bridgeport states its fittings meet OSHA-recognized NRTL-listed electrical standards. Give the inspector the file number if they ask for listing documentation.
4) Is the RACO 4734 SWIVEL-LOK connector an equivalent to the Bridgeport 642 series clamp connectors?
No. The Bridgeport 642, 643 and 645 are two-piece clamp type snap-in connectors in zinc electro-plated steel, used to connect non-metallic cable to a box or enclosure with no locknut required. The RACO 4734 is a 1 inch Type B liquidtight multi-position connector made of nylon in the SWIVEL-LOK Series. If the run is liquidtight flexible conduit rather than non-metallic cable, the 4734 is the connector that matches the raceway; for NM cable into a knockout, the Bridgeport clamp connectors are the right family.
5) Will a zinc plated steel connector hold up in a damp basement or unheated garage?
The body is steel with a zinc electro-plate finish, which Bridgeport describes as rust and corrosion resistant. The FB-1 rating is the standard for fittings and boxes, not a wet-location enclosure rating, so treat these as dry and damp interior fittings and use a listed liquidtight or wet-location fitting for direct exposure to water.
6) Are Bridgeport 642 series connectors made in the USA?
Yes, they are manufactured in the United States, which is the detail that matters if you are buying against a Buy American or domestic-content requirement on a government or institutional job.
7) What is the largest cable the Bridgeport 645 connector will take?
The 645 is the biggest of the three, clamping cable up to 1.125 inches and seating in a 1-1/2 inch knockout. Anything above that diameter needs a larger fitting family.
8) I need a 4 inch square box with the cable connector already built in - what should I order instead of a loose Bridgeport connector?
The RACO 232MSCM is a 4 in. square welded box, 2-1/8 in. deep, with an integral STAB-IT connector and an M bracket, so the cable termination is part of the box. The Bridgeport 642 series are loose two-piece clamp connectors that install into an existing knockout, sized 1/2 inch, 3/4 inch and 1-1/2 inch. Choose the RACO box when you are setting new boxes and want the connector integrated, and the Bridgeport fittings when the box is already in place.
9) Can I use a Burndy BONDIT BDTIBB in place of a Bridgeport cable connector?
No - they do different jobs. The Burndy BDTIBB is a wall mount intersystem bonding connector in stainless steel for #14 to #2 AWG conductors, used for bonding communications and grounding systems at the service. The Bridgeport 642 series are steel clamp connectors that terminate non-metallic cable into a box or enclosure knockout. A bonding connector will not secure a cable entering a box.
10) Can I use one of these connectors instead of the built-in clamps on a metal box?
Yes. A box like the RACO 232MSCM 4 inch square welded box uses built-in STAB-IT connectors, but where a box has plain knockouts instead, the Bridgeport two-piece clamp gives you the same job done at the knockout with no locknut. Match the connector to the knockout diameter and the cable diameter.
11) Do I need a Burndy Tapit cover with the Bridgeport 642 connectors?
No. The Burndy UCCOVER1BOX25 is a polyethylene cover for Tapit tap connectors, which are insulation-piercing taps on conductors. The Bridgeport 642, 643 and 645 are UL listed under file E11698 and NEMA FB-1 rated fittings that clamp cable at the enclosure wall, so the enclosure itself provides the enclosure of the connection and no separate connector cover applies.
