Armyrdr... How would one go about raising the door higher or adding another piece to the door?
1. Saw off the metal lip at the top of the door and replace wood in door with taller piece. Be sure to make smooth edges around door corners because we just never know what he could do back there.
2. Add a small metal piece with wood with new hinges and new lock on the opposite side. Like a mini door.
3. Fabricate taller door, all one piece. No new hinges required and it would probably look neater.
I think any half decent welding shop could do the last 2 options.
