What Is a Prehung Door?
A prehung door is a complete door unit already mounted on its frame, often with hinges attached and pre-drilled holes for hardware. It includes:
- The door slab
- The door frame (jamb)
- Pre-installed hinges
- Lockset holes (optional)
- Weatherstripping (for exterior doors)
This makes installation easier and faster, especially for new builds or frame replacements.
