Terrible product - no support - company provides no way to contact - track size is not stated - you have to assemble doors - ours did not fit together properly - and in the end they did not meet in the middle - over an inch gap at the top when touching at the bottom. No easy way to adjust - these are really poorly done - you do not know about these issues until after spending the time to put the doors together and then trying to hang them - how does one then go about returning assembled doors and mounted track - unless you are handy at improvising these are a mess - and yes would not ever buy them again
