Hi. I had great expectations of this product, given the price and the data available on your website, but am overall really disappointed with my purchase. The appearance of the doors are nice and the quality of the fittings are very good. The doors are easy to install BUT.... I purchased the doors with a threshold--the thought behind this was to provide additional stability when opening and closing the doors. The lack of a drop bolt at the foot of the pivot door panel supporting the middle access door means that the two connected doors are "floppy" when opening and closing. Rather than having a solid support at the base of that pivot door the whole system does not feel solid at all--giving it a "cheap feel". Additionally, I purchased a Bifold Door catch kit (the metal door holders set). The fit is extremely tight so when trying to pull the access door away from the pivot door not only is it a fight to release the catch but the lack of that drop bolt, as highlighted above, means again the doors are "flopping about". Sorry for using a word such as floppy--I can't think of another adjective to describe the action. To overcome this situation I am going to have to employ a carpenter to route a recess for a drop bolt and associated striker plate on the supporting pivot door to give the doors some stability. Very, very disappointed. I have added a photo to try and help support this description.
