1 Hour UL Wall Assembly U340 - alternative

[RPM001]

My plans spec U340 which is a 6" wide 1 hour wall assembly that is framed using 2x6 and 2x4s and a single layer of 5/8" Type X drywall.

Is anyone aware of a 6" wide wall assembly that uses metal track & metal studs instead? I know there are plenty of metal stud/track assemblies but most of them are for 3 5/8".

UL states that stud sizes are minimums (see https://iq.ulprospector.com/en/profile?e=206790#SectionVIitem4).

U419 get you there?

you beat me to it, 419 covers a lot of situations, defiantly my go-to UL wall assembly.
