Hey y'all.
I'm looking for an insulated standoff for a wire for a ground scheme for tube amps. The idea is to have a ring ground like structure where multiple connections are made to various single points, these points go to a twisted pair of 20AWG tinned copper wire and then there is one ground point near the input (like what Psionic Audio has suggested in his videos).
I'd like to be able to mount this twisted ground wire around the component board, and obviously not touch the chassis, so I need some sort of stand off that physically raises and holds the wire in place.
Something like this, but much smaller (obviously) and chassis mounted.
Any idea where I could get this/what it would be called? Thanks in advance!

These guys have a selection of stuff that may be suitable. This is not a recommendation as I haven’t used them, but should give you an idea of what to look for. https://talonelectronics.com/shop/category.aspx?catid=288
I'm in Ireland, just as you are, so it would seem 😉 do you have any recommendations with shipping from this side of the atlantic?
Sadly, no! I had a quick look at Farnell and couldn’t see anything suitable. I’ll have a dig around and I’ll let you know if I find something in the next day or so.
Why not use the square zip tie sticky mounts? Place them where you want to route the ground wire and use zip ties to hold it in place. No need to drill holes and use screws with insulators as the mounts are nylon as are the zip ties.
I saw em in a video, maybe also Psionic Audio lol, and they looked extremely neat and professional. I have no qualms with drilling/riveting into chassis hahah
Not a terrible Idea but I would then have to heat shrink the wire in appropriate places. Not the worst thing in the world, but it'd be a hassle if there was a purpose built part for this job.
These are sturdy, safe, have metal M4 thread at both sides for screw connections to both wire lugs and chassis, are insulated (appear not to be but they sure are) and often used in environments where stuff vibrates. Industry standard and used in industrial switch panels. A plastic wire clamp M4 or nylon/metal eye bolt M4 possibly secured with an M4 nut can be used to hold cabling/wiring together. Length is 15 mm, the hole is not continuous.
In short not suitable 🙂

Looks like just the ticket. I wonder if I can find similar ones that offer more suitable mounting options.
These I found on Ebay and I've soldered my round bus to the forked ones.
I made these by soldering a few ground lugs together with a brass nut underneath. You could then mount to a nylon threaded standoff or use a standoff with a stud on one end and female threads on the other.
Here are some on US Ebay :

A lot of these are good solutions, but I cannot get it out of my head that I saw something very professional looking that was kind of like a raised p clip with a circular plastic insert in it for a wire to go through... I may be going fully mad though, so who's to say?
Maybe something like this would be ideal.
12 inch cable diameter though, that's pretty excessive. Would be great if something like this existed in the 2-3mm range.

FYI: not sure if this applies...

If mounting hardware is used and works OK in certified electrotechnical installations it will work OK in DIY stuff. For some reason some builders search for solutions that have yet to be invented it seems 🙂
Metal chassis are to be recommended for safety and to shield against today's RF all around you. A 3.3 mm drill and M4 thread tap are then necessary. Of course the chassis is connected to the PE pin of the IEC inlet.
