PCB fasteners perpendicular to heatsink

[Baffless]

Hi,
Can't find hardware to fasten PCB which is perpendicular to heatsink. Something similar like with LM3886 chips used on Modulus Amps.
The chips are on the market, believe some hardware to fasten PCB should also be available...Any ideas where to find?

I had those brackets custom made for the Modulus-186 and Modulus-286. They weren't cheap, but also not silly expensive. Though, if you only need one pair they'd be silly expensive.

Keystone makes a lot of mounting hardware. Search on Mouser and you shall find.

You can combine off the shelf L-brackets to do what you want. Keystone does have a good selection.

Keystone 4336 worked great in the Bob Cordell Super Gainclone build. (link). Also good for the "Compact3886" build. Scroll down to the Parts List attachments and take a peek.

I'm sure you will have your own opinion about the suitability of these easily available parts.

These small could be ok if pcb is not large. But i need larger
