What is a multipoint lock?
A multipoint lock latches into the doorframe at several points to provide added security. Commonly, a multipoint lock has strikes on the top, middle, and bottom of a door leaf, with the top strike either latching to the side jamb, a passive door panel, or the top jamb, and the bottom strike latching to the side jamb, the sill, or a passive door panel.
Multipoint locks increase the security of a door, give greater structural integrity to the panel, and decrease the likelihood of warping. Trim packages (the visible parts of the lock) are available in a wide variety of designs and finishes.
