Alternative to the Myers Hub

Are you terminating conduit to equipment on the inside wall or just passing though wall to equipment further inside? Or stubbing into a transformer room?

Why not just pass though wall and seal with silicone? Silicone is a wonder drug in most cases. Sounds like someone is needlessly overdoing this.

Is there room to cut squares just big enough for the hubs that can have a thinner chunk of metal bolted to the 1/2" plate and scilicon sealed? Or welded

Getting close!

If fabricating the enclosure - weld a coupling to the enclosure wall. Should be no need for a grounding bushing as the coupling is now effectively a part of the enclosure, can still leave full opening and thread a chase nipple into the interior side if an abrasion bushing is desired.

Winner, winner, chicken dinner! Back in my skid work days in the factory, we welded 3000# couplings to holes in the web of beams to get out of the skid.

The problem is that these locknuts do not provide a grounding lug.

Several thoughts:
1) Contact Eaton and see if they can supply loose PVC gaskets which could be used with their 'bonding locknuts'.
2) Fabricate a thin sheet metal component with a bonding lug on it, that would fit under the sealing locknut to provide the grounding connection.
3) Simply 'stack' a bonding locknut over a sealing locknut.

On this link I see an option for a four inch bonding locknut, that could replace the locknut for the Myers hub on the inside of the module and use a compression lug on your jumper to go under the screw of the bonding locknut. Looks a lot thinner that a Myers hub locknut giving you some room to play with. A 5" penetration? Makes me wonder if the Myers hub will cover that.
