3 Doors oversized for opening bad design I believe the installation should have been a 4 door as the weight of the three falls to the one side so you can’t open the doors without a struggle and sometimes impossible to close properly to lock them installation perfect but product badly designed , Origin as so many other customers have received complaints but really not interested they always blame the installation not there product they won’t even come out to look at the problem I would not recommend them to anyone kind regards from chris watson at SA68 0xe and if there’s any one out there that could sort these bifolding doors out please contact me on 07957718906
