Crouse-Hinds PLG2 SA – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds PLG recessed conduit plug come in?
The PLG recessed plug runs the full range from 1/4 inch up to 4 inch trade size: 1/4, 1/2, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3, 3-1/2 and 4 inch. The catalog number tracks the size, so PLG1 is 1/2 inch, PLG2 is 3/4 inch, PLG3 is 1 inch, PLG4 is 1-1/4, PLG5 is 1-1/2, PLG6 is 2 inch, PLG7 is 2-1/2, PLG8 is 3 inch, PLG9 is 3-1/2 and PLG10 is 4 inch. The 1/4 inch is PLG28, which breaks the pattern, so order it by that number rather than guessing.
2) Can I use a Crouse-Hinds PLG plug in a Class I Division 1 area?
That is exactly what the PLG plug is built for. It carries a Class I, Division 1 NEC hazardous rating and is listed for hazardous/classified locations under NEC/CEC standards. Division 1 means ignitable concentrations can be present under normal operating conditions, which is the harder of the two divisions to satisfy, so the same plug is equally acceptable in a Division 2 area on the same system.
3) What does the SA suffix mean on a Crouse-Hinds PLG conduit plug?
SA is the copper-free aluminum version. PLG6 is the standard steel plug in 2 inch; PLG6 SA is the same 2 inch plug in copper-free aluminum. Copper-free aluminum is what you specify where copper or copper alloys are restricted, which is common in refinery, chemical and acetylene-adjacent work and in some corrosive process areas. If your spec does not call it out, the plain steel number is the one to order. SA is offered on 1/4, 1/2, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3, 3-1/2 and 4 inch, so it is not a size-limited option.
4) I need to plug an unused hub on a hazardous location junction box. Is the PLG plug the right part?
Yes, provided the hub is a threaded rigid or IMC opening. The PLG closes off unused threaded conduit openings and is rated Class I, Division 1, so it does not downgrade the classification of the enclosure it goes into. Match the plug trade size to the hub size, not to the conductor or the conduit you were originally going to run.
5) Does a conduit plug count as a seal for Class I Division 1, or do I still need a sealing fitting?
A plug and a seal do different jobs. The PLG closes an unused threaded opening in a rigid or IMC system and is rated for Class I, Division 1 service. It is not a conduit sealing fitting and does not satisfy the NEC requirement for seals at enclosure entries and boundary crossings. If your drawing calls for a seal at that point, you need a sealing fitting; the plug only closes the hole.
6) What is the difference between a recessed conduit plug and a hex head plug?
The drive is the difference. The PLG is a recessed plug, so the driving feature sits down inside the plug body rather than standing proud as an external hex. That keeps it low profile, which matters where the fitting sits in a walkway, near moving equipment, or anywhere a projecting head would catch a hit. The tradeoff is that you drive it with a tool that engages the recess, not with an open-end wrench on flats, so bring the right driver to the job.
7) Is the standard Crouse-Hinds PLG plug steel or aluminum?
Steel, unless you order the SA version. The base PLG numbers (PLG1 through PLG10 and PLG28) are steel, which gives you mechanical strength and corrosion resistance for industrial service. The matching SA numbers are copper-free aluminum. Both cover the same 1/4 inch through 4 inch trade size range.
8) Which trade sizes of the Crouse-Hinds PLG plug are available in copper-free aluminum?
Every size. Copper-free aluminum (SA) is offered across the whole 1/4 inch to 4 inch range, so a facility that standardizes on copper-free hardware can carry SA plugs for all its conduit sizes without falling back to steel on the odd size. The 1/4 inch SA is the small end, and the 4 inch SA (PLG10 SA) is the large end.
9) Are Crouse-Hinds PLG plugs acceptable for Canadian jobs?
They are built to NEC and CEC standards, so the same PLG number works on both sides of the border for hazardous classified location work. Your AHJ still governs the installation itself, but the plug is not a US-only part number.
