Abstract
A multi-point lock and method for locking with two remote mortise locks operated by a central actuator to which they are mechanically linked. The mortise locks are mounted with opposite orientation so that they simultaneously engage separate keepers from opposite directions. A housing of the multi-point lock is adapted to allow the placement of mounting screws along the entire length of the lock.

A multi-point lock which may be used for a sliding glass door comprising:
- a central actuator hub;
- a linkage assembly pivotally engaged with said central actuator hub, said linkage assembly having two linkage rods, wherein said two linkage rods comprise a straight actuator link and a dog leg actuator link;
- a first and a second remote actuator, wherein said first remote actuator is pivotally engaged with said straight actuator link and said second remote actuator is pivotally engaged with said dog leg actuator link;
- and
- a first mortise lock having a first hook that engages a first keeper when said first mortise lock is actuated and a second mortise lock having a second hook opposed to said first hook that engages a second keeper when said second mortise lock is actuated, wherein upon rotation of said central actuator hub, said straight actuator link rotates said first remote actuator which in turn actuates said first mortise lock, and said dog leg actuator link rotates said second remote actuator which in turn actuates said second mortise lock.
