I need to hang an exterior door in a wall that's a total of 10-3/4" thick, from face of drywall inside to face of exterior trim outside. I need a threshold that spans 11" or maybe a bit more. The door swings in. I usually use Pemko residential thresholds, but the widest I can get is about 8-3/4", using a 5-3/4" threshold and a 3" extender. I have considered making my own, out of rift white oak, or modifying one of the Pemko models that is wood/aluminum by adding more wood to it. Any other…
