Things to consider
- Mortised on frame and surface mounted to recessed channel in door
- Special 3/16” backset on frames – check template!
- Expensive prep on frames and doors
- Make sure your manufacturer is experienced with preps for this pivot
- Minimum 2″ face for single return profiles
Red flags
- Locations will be needed if ordering a frame
- Extremely tight clearances – will likely need to grind off hinge corners
- Hinges must be installed on door prior to hanging in frame
- Mounting strip recommended for accurate hinge placement
- Consult manufacturer for KD drywall applications (2 1/2″ face minimum & other considerations)
- Experienced door hangers only – very tricky installation
