Conclusion of סוגיא צורת הפתח – כיפה – arch
Question:
Why is an arched door frame which starts to arch from the bottom of the side posts not obligated in mezuzah?
Is it only when lacking width of 4 tefachim with a minimum height of 3 tefachim or is it because a door frame needs to have straight side posts and a flat lintel?
Is a doorframe which is wider than four tefachim that begins to arch from bottom of the side posts considered a צורת הפתח ?
