Larger DC Jack help

[mattpas]

Does anyone know where I can find barrel-style negative tip 2.1 DC jacks for a .6 inch / 15mm hole?

There's this type

https://benselectronics.nl/dc-power-jack-5.5x2.1-mm-inbouw/

Drill hole: 11.5 mm
External flange size: 14 mm                             <<<<<-------- That's going to go straight through a 15mm hole!
Required installation depth: 17 mm

I think I have seen this style with 13mm hole but not 15mm.
