To remove an internal folding door, you’ll need to release the locking lever, if your door has one, and slightly raise the door off the floor or track. Once lifted, you’ll need to remove the bottom pivot bracket. For safety, you may require two people for the job.
When the bottom pivot has been removed, move the lower half of the doors so that the pin isn’t over the bottom pivot bracket. In doing so, the top pivot pins will slide out of the top bracket. If you’re having some trouble, try tilting the door at different angles until the pivot has popped out of the bracket. Your bifold doors should now come away from the wall.
Unscrew the guide and pivot assembly at the top of the door, and then repeat this for the bottom.
If you’re planning on putting the internal bifold doors back, do not unscrew the guide and pivots.
