Frameless Door Sizes and Rough Openings

Frameless Door Rough Opening Details

The Rough Opening for Frameless Interior Doors will look like a standard Rough Opening as for any other door.  The wall depth can be anything from 4" - 12" with common depths being 4 9/16" and 6 9/16".  Frameless Door Frame Depths can accommodate a variety of wall depths and are usually always smaller than the wall itself.  Drywall returns will finish off the difference between wall and frame dimension. The drywall can be finished right to the Rough Opening edge the same way you would have the wall prepped for regular doors.  Finished floor can either be on or off when Frameless Door installation takes place.
