I am looking for a 10ga power cable holder/retention devicefor my chassis. I want to run the power cable straight in with no IEC connector, and I can't seem to find connector that will fit around the cable and keep it attached to the case. I have seen them on a bunch of commercial amplifiers, but I can't find out what they are called. I assume that mcmaster.com or somewhere must have them.
Here is a picture of the back of a Krell amplifier that has a 10ga wire going straight in with no connector. What is this attachment device called?

maybe you're looking for this...
hi
i believe those are called 'grommet's, a cursory google search revealed, for example...
http://www.danchuk.com/firewall.wire.harness.grommet.html
(don't know what gauge this grommet is for, they don't specify).
also, i've found that a good source of ultra-thick cable for things like power etc is welding cable - gauge 2 to 6 are in fact easy to find home depot and such, who also have nice thick copper lugs to accept such thick gauge wire (you can find this stuff in their welding supplies section).

Re: maybe you're looking for this...
Thanks for the advice. I picked up some of their 10ga heavy duty power cable for $0.88 a foot, so this should do. It is quite thick and heavy. I was looking at some huge Krell amplifiers at a local audio dealer, and they had the exact same power cable on the back of them with the grommet thing that you talked about.

hi again
that's just a different design i guess - allows multiple-use?
the one's i've usually seen in electronic equipment are one-time use only - you pass the power cable through the grommet, through the chassis hole and solder/clamp it into place inside the amplifier. then you have to wrestle the (rubber) grommet into the chassis hole so that the ring-like depression in it snaps into the chassis hole, which must previously have been cut to be the appropriate size: larger than the grommet's inner diameter, but smaller than it's outer dia. you can see the ring-depression on the grommet in the above picture. only method of disassembly would be to cut the grommet apart.
the two-piece snap-in types would potentially allow easy disassembly, but i'm not sure if you'd want that in a strain-relief
hope this helps -

I am thinking of using one of these:
Nylon Liquid-Tight Cord Grip Fittings
It should work just fine. I assume that it is liquid tight, that it will provide a tight connection to the chassis for cable retention. Anyway, the amplifier will just be sitting on the shelf and pressure shouldn't be placed on the cord.

Yes. These are standard connectors - we used to call them Hub connectors but that may not be technically correct. They're used when you need to run a flexible cable into a junction box.pinkmouse said:It might also be worth checking out your local electrical wholesaler
