Crouse-Hinds CRS-390 – Frequently Asked Questions

1) Which trade size Mark 9 blank cover do I order for a 3/4 inch Condulet body?
For a 3/4 inch conduit body, order the Mark 9 blank cover catalog number 290. The sheet aluminum Mark 9 blank covers run by trade size: 190 for 1/2 inch, 290 for 3/4 inch, 390 for 1 inch, 490 for 1-1/4 inch, 590 for 1-1/2 inch, 690 for 2 inch, and 889 covering 2-1/2 inch through 3 inch. Match the cover number to the trade size of the body, not to the conductor size.
2) Can I use a Crouse-Hinds Mark 9 blank cover in a hazardous or explosion-proof location?
No. The Mark 9 sheet aluminum blank cover is rated for ordinary, non-hazardous locations only. For Class I or Class II areas you need a cover and body assembly specifically listed for that classification, with the gasketing and fastening that listing requires. Putting an ordinary-location blank cover on a hazardous-location body voids the assembly.
3) Will a sheet aluminum conduit body cover hold up outdoors or in a damp plant environment?
Sheet aluminum resists corrosion well, which is why it is used on Condulet covers in wet and washdown-prone commercial and industrial runs. What it does not do on its own is seal the body. Weatherproofing comes from the gasket between cover and body, so if the location is wet or exposed, make sure the body is gasketed and the cover is drawn down evenly on all fasteners. The cover itself carries no rating beyond ordinary, non-hazardous locations.
4) Does the Crouse-Hinds Mark 9 blank cover meet code for a commercial electrical inspection?
The Mark 9 blank conduit body cover is built to NEC/CEC standards, which is the reference an inspector works from on both sides of the border for conduit body closures. A blank cover is the correct way to close an unused opening on a conduit body; leaving the opening open is a violation regardless of the hardware used elsewhere on the run.
5) I'm standardizing covers across a facility, do these blank covers include a gasket or screws?
These are blank sheet aluminum cover plates only. Gaskets and cover screws are separate items, so when you stock Mark 9 blanks across a facility, stock the matching gaskets and screws by the same trade size at the same time. The seven cover numbers (190, 290, 390, 490, 590, 690, 889) cover 1/2 inch through 3 inch, which is most of a typical commercial branch-circuit conduit range in one part family.
