Chase nipple between cabinets

[electrofelon]

Is there any issue butting up two cabinets and using a Chase nipple? There's something I don't like about it but I can't really state what it is. I kind of want to put a locknut between the two.

These work nicely for metal outlet outlet boxes. I have only seen them up to trade size 3/4. Since you said cabinets, I assume you want something larger. I have seen 2 chase nipples used in combination with a threaded coupling. I believe that technically is a listing violation.

But I would use a locknut between cabinets just to provide that little space, like you said. Or if you prefer a bit more, use a close nipple.

Wouldn't having two locknuts in between be better, particularly with the locknuts that have sharp points on only one side (and so the sharp side would face the cabinets)?
Is there a box spacer available for the size you need?

So this is larger, 4" and service equipment.
A CT cabinet and a swichboard. The locknuts are bonding locknuts on the CT side.

I was going to say bonding is the only issue, but since it is service application aren't both cabinets bonded to the grounded conductor anyway? All you need is a bonding bushing/locknut/etc to assure bonding of the nipple - only because it is containing service conductors. If it were a feeder and no eccentric/concentric KO's only a standard locknut is needed. Bonding jumper between cabinets may still be needed if the cabinets are coated/painted. If unfinished/galvanized their direct metal to metal contact along with tightening of the locknut(s) is a sufficient bond between cabinets.
