Excellent, frindly, efficient, speedy service, for which, we gaave just recently installed the Bi Folds, which look are work absolutely great. I do however have one problem, which I'd appreciate your advice or help on, if possible? WE have a 4 door unit, opening on the right. When open this door can freely swing in any wind. Do you have any proidutc, door latch, or where I could find one that opnes, hionged on the roght, where I can buy a patch, to attach to the door handle and wall. Alkl. thos available so far are for doors attached to a wall on the left.
