Title: Zip ties instead of stand offs
Post by: Willabe on February 23, 2016, 12:11:31 am

I found these zip ties with a molded mounting hole. Took a little searching to find them with either a #6 or #4 mounting hole but they do make them.

I'm going to try them for mounting the loose end junction of preamp tube grid stoppers and shielded cable. I probably need to slide some shrink tube over the loose end of the R/solder joint to keep it from shorting out to the chassis?   

And then I found these zip tie mounting brackets, they will hold 2 separate ties, only need 1 bolt/nut and only 1 hole drilled in the chassis. These have the benefit of lifting the R off the chassis depending how you mount them. Gonna try them too.  :icon_biggrin:

Both are cheaper then stand offs so I can save those for high(er) voltage stuff.

Thanks DL, yeah guys here have been using those and posting gut shots with them.

But, I want to bolt them in, I just don't trust the adhesive/glue to stick long time.

Not sure about the *modern* glue, but the stuff we used in the 80's I had to chisel off in the 2000's so the scrap metal buyers were happy

That's the way it always is when you want to remove them!   :icon_biggrin:

I've used quite a few of those throughout my career. The ones used in a fully climate controlled space do very well. The ones in a weatherproof junction box in the parking lot usually turn loose pretty quick.

The mounting hole zip ties and bolt down zip tie mounting blocks arrived in the mail.   :mail1:

I really think these are going to work great!  :icon_biggrin:

Zip tie bolt hole is a #4 and the mounting bracket is a #6.
