The manual side latches mounted on each side column secure the door in the closed position.
When latched in place, the door is tight. The side latches are adjustable and easy to install. The
door must be manually unlocked before the door can be opened and manually relocked after the door is in the closed position.

The Latching system is one lever operated from one end of the bi-fold door,
latching both sides to a fully locked in position. Saves many steps.
