Bi Fold Door Hinges
National V530 3" (76mm) Bifold Non-Mortise Hinge - PAIR (Satin Nickel)
I have 4 sets of bi-fold doors that are about 9 years old. They are quality, solid, shaker style - the interior panel (the panels in the middle) have all sagged about 3/16 - 1/4". I want to replace the hinges and level them before they are painted. What type of hinge and how many should we use to prevent this from happening again. One section consists of two connected panels, 78" X 15". Thanks in advance for you help.
