Bridgeport Fittings BF-921 – Frequently Asked Questions

1) What conduit sizes do Bridgeport malleable iron rigid nail straps come in?
Four sizes cover the common EMT runs: 1/2 inch (part 920), 3/4 inch (921), 1 inch (922) and 1-1/4 inch (923). Match the strap size to the trade size of the EMT you are strapping, not to the outside diameter you measure.
2) Are these nail straps for EMT or for rigid conduit?
Bridgeport's malleable iron nail straps are specified to support EMT to a mounting surface. The "rigid" in the name refers to the strap body being a one-piece rigid malleable iron casting rather than a formed steel clip, so size them to EMT trade size.
3) Are Bridgeport nail straps UL Listed for a commercial electrical inspection?
Yes. They are UL Listed under file E161206, which is the number an inspector or submittal reviewer will want on the paperwork. Bridgeport also states RoHS, REACH and LEED compliance, which matters on institutional and LEED-tracked projects.
4) Will zinc electro-plated straps hold up in a damp basement or parking garage?
The zinc electro-plate finish is there for corrosion resistance over time, and it is suited to interior and sheltered commercial work like garages, basements and light industrial spaces. For direct exposure to weather, standing water or chemical washdown, a strap specified for that environment is the better call, since electro-plate is a thinner coating than hot-dip galvanizing.
5) Why choose a malleable iron strap over a stamped steel one-hole strap?
Malleable iron is the heaviest-duty option of the two. It has the strength and rigidity to hold a run without deforming, and it can flex under load instead of cracking, which is what you want on long horizontal runs, heavier fill, or anywhere the conduit gets bumped. Stamped steel straps are lighter and fine for short residential runs; on commercial and light industrial work the iron strap is the one that survives.
6) Do nail straps come with the nails, or do I supply the fasteners?
The Bridgeport 920 through 923 straps are sold as the strap only. Plan on supplying your own fasteners sized to the substrate, masonry anchors or screws for block and concrete, and the nails or screws your spec calls for on wood framing.
7) Can I standardize on one nail strap across a whole multi-family or MRO stock room?
Stocking the 1/2 inch (920) and 3/4 inch (921) covers most branch circuit EMT in apartments and offices, with 1 inch (922) and 1-1/4 inch (923) for feeders and homeruns. Same malleable iron body, same zinc electro-plate finish and the same UL file E161206 across all four, so your submittal package and your finish stay consistent regardless of size.
8) Is the Cantex 5133330 PVC wallplate an alternative to a Bridgeport malleable iron rigid nail strap?
No. The Cantex 5133330 is a PVC single toggle switch wallplate, a device cover that mounts over a switch at the finished wall surface. The Bridgeport malleable iron rigid nail straps in 1/2 inch, 3/4 inch, 1 inch and 1 1/4 inch sizes are conduit support hardware, used to support EMT to a mounting surface, and are made of malleable iron with a zinc electro-plate finish. The two serve entirely different points in an electrical rough-in and cannot be swapped for one another.
9) Where are Bridgeport malleable iron nail straps made?
Country of origin is China. That is the detail to confirm against any Buy American or domestic-content requirement on federal, transit or other publicly funded work before you submit these.
