The Schlage ALX Series is a grade 2 lock unlike any other. Designed to exceed expectations, it features a single, patent pending chassis design that supports most functions and all cylinder applications. As a modular lock, ALX Series enables in-field function set up or exchange plus a field-selectable Vandlgard feature on all locking functions. Exceptional durability comes from a stainless steel latchbolt, deep-drawn spindles with 5 points of lever engagement and the use of Grade 1 compression springs that prevent droop and wobble. Perfectly suited to the ND Series grade 1 locks, ALX allows you to seamlessly suite between the two to gain grade 1 strength, security and functionality when and where you need it right alongside ALX as a budget saving grade 2 solution elsewhere in the building.
