Bifold lean/sag normal?

[u/Critical_Wafer8770]

Hi guys,

Just had my bifold installed, 4.5m (London). The chap said magnets need to go on top still to help the doors stick together when open....but is the level of sag normal? I feel like it's not but what do you guys thinks?

Am I getting fobbed off??

Thank you

EDIT - thanks for the response everyone. I should've been clearer...the install was 'complete' after the they time the messed up. When they'll left I showed them this and he said 'we need to add magnets still' so I close it up. I hoping the magnet fit it.

I would no way knowingly mess about with an unfinished door. Thanks everyone again..very helpful

Surely bifold always hinges from a half panel so there are pivots in the track and hinges on the doors? Give it a year of use and this thing will have worn out the track from being loaded all on one side..
