jamb width 84' interior door?
I went to HD tonight to price out our interior doors (pre-hung). When the salesperson clicked through the options the stand jamb width was 6 and 9/16! We have 2x metal studs with 5/8" drywall, so I don't know how I could make this fit.
The "true" standard (2x + 1 inch for drywall) is a $50 (about a 40 percent) upcharge. Very unappealing. Why is 6 9/16 the standard width?
