Crouse-Hinds CRS-512 – Frequently Asked Questions

1) What trade sizes do the Crouse-Hinds malleable iron one-hole conduit straps come in?
Eleven trade sizes, from 1/2 inch up through 5 inch: 1/2 (510), 3/4 (511), 1 (512), 1-1/4 (513), 1-1/2 (514), 2 (515), 2-1/2 (516), 3 (517), 3-1/2 (518), 4 (519) and 5 inch (520). Order the strap by the trade size of the conduit, not by the outside diameter you measure, since rigid and IMC are both called out by trade size.
2) Can I use these Crouse-Hinds conduit clamps in a hazardous or classified area?
No. These malleable iron one-hole straps are rated for ordinary, non-hazardous locations only. For a Class I or Class II classified area you need support hardware specified for that classification.
3) Can a Cantex 5133 one-hole strap be used in place of a Crouse-Hinds 510 series malleable iron clamp?
They are built for different raceway systems. The Crouse-Hinds 510 series is a malleable iron one-hole strap for rigid and IMC conduit, offered in trade sizes from 1/2 inch through 5 inch. The Cantex 5133 series is a one-hole PVC conduit strap, listed in a 4 inch size. If the run is rigid or IMC metal conduit, stay with the malleable iron 510 series clamp; the PVC strap is sized and intended for PVC conduit, so a crossover is only appropriate if the raceway material itself changes.
4) Is a malleable iron strap worth it over a stamped steel one for a commercial conduit run?
The difference is the body. These are malleable iron rather than formed sheet, which is what electricians reach for on heavy rigid and IMC runs where a thin stamped strap can distort as the mounting screw is pulled down. The one-hole pattern also means a single fastener per support point, so layout and drilling go faster on long runs.
5) Will these straps satisfy an inspector for conduit support under the NEC?
The straps are built to NEC and CEC standards as a conduit support product. Compliance on the job still depends on your spacing: the code sets maximum support intervals and a strap within a set distance of each box or fitting, so the strap choice gets you there only if the layout follows the support table for the conduit type.
6) Does the mounting screw or anchor come with the conduit clamp?
No fasteners are supplied. Each one-hole strap takes one fastener, and you choose it for the substrate: a machine screw into a threaded insert or strut, a self-tapping screw into metal stud or deck, or an anchor in concrete or masonry. Order the fasteners separately with the straps.
