Exterior door rough opening
I am about to frame up a rough opening for a pre-hung, exterior door. It is a French door and has exterior trim preinstalled.
I have things saying everything from the opening should be 2" wider and 2" taller than the measurments of the frame to 1/2" to 3/4" wider and taller... and every combination therein.
Anyone have a standard that works for them?
