Passlabs Preamp Envelope Design - High-Grade Outline by only 10 parts except Screws

[tiefbassuebertr]

Passlabs envelope design - high-grade outline and very easy at the same time.
I like this design much more than all the other (especially than the often to find profile enclosure systems with bad quality metric threads in the aluminium).

The envelope of these high quality models consist basically of 10 elements:
- front-panel,
- rear-panel,
- 2x side panels so as
- bottom cover and
- top cover - so as
- four connecting devices therefore, fitting with metric threads, each from four surfaces (see attached image).

What is the colloquial term of this connecting devices?
Are this connecting device even made by default (thus available as standart part) or purely custom-made?

Thank you for your advices.

They are machined from aluminum for us.

We have used these sort of corner blocks since 1991. The refined chassis
you see now is the work of Desmond Harrington, who joined the company in
1996. You may recognize his style from the glory days of Krell.

As Nelson said, "corner block." I've used the terms threaded corner block, corner cleat, mounting block, etc. (but not "bracket," nor "brace.")

Seems there's no standard term or off-the-shelf parts available (at least from McMaster-Carr...)

You can find it under square rod's in distributor catalogs that has engineering materials, I know RS stocks a few types, yo uwould need to cut, drill and tap it though.

"Rod" is a geometrical term for solid cylinder, and >technically< the type of bar stock known as 'rod' is always round. The bar stock we want here is square bar (or rectangular bar).

RS sell square bar

And me was thinking to have had an original idea

Unless you need quite a few of those, it will take longer to buy them and pick them up at the post office, than to just make them yourself.

My bad, my english dropped me for a second there, I meant to not use the word tube, as those are hollow, and then I came up with rod instead of bar....

You could also order from clickmetal for smaller pieces.
