rehanging bifold door + safety

In a attempt to rehang a bifold door that my 4yr old daughter somehow managed to knock off the track, it seems the door is now about 1-2'' too short to hang. I am not sure why the door is not fitting, which was orginally bought from Menards and currently I do not know the name of the Mfg.

The top pivot and roller guide are spring loaded, so when I place the door into the lower pivot bracket, the top pivot and guide are about 1-2'' below the top pivot and track, so the door can not be mounted. From what I recall all hardware is still present as I was in the room at the time it was knocked out and did not find any pieces, and the top pivot and roller guide cannot be extended out any further.

Q1) Any ideas on how or why the door height is no longer the proper mounting height, and how I might be ablt to adjust?

Q2) Any ideas on how to prevent this again as the door fell to the floor and could have fell on to someone? Without too much detail from what I can tell it seems my daughter was able to get a mop type stick under the bottom and created enought leverage to push the springs up and then the door shifted and fell out/down. I would definately like to prevent this from happening in the future if possible.

I am going to contact Menards tomorrow to identify the Mfg so I can provide additional details and the specific hardware required for proper installation. Thanks for any suggestons.

 

It sounds as if the lower adjustable pivot was driven up into the wood. You should be able to adjust the door about one inch. The adjustment comes from screwing it out from the bottom. The top two spring loaded pins will move up accordingly.
Bifold doors leave nothing to safety, as they will pop off quite easily with minimal pressure. You may not be able to make the door safer, as it seems kids can dismantle almost anything, if you know what I mean.

 

Perfect asessment, that was it Although I am somewhat surprised that the adjustable pivot was driven up into the wood so that it was flush, considering that it now needs to extend about 1 1/2 ''. It did not seem stripped or other noticable damage. Hopefully now the kids can focus their energy on their next 'project'

Thanks for the feedback
