The toughest leverset for heavy-duty commercial applications.

At Schlage we know that every product you specify has to stand up to constant use and abuse without compromising security. The ND-Series gets the job done with tough, dependable ANSI Grade 1 locks designed for use in schools, hospitals, offices, retail spaces, and colleges and universities. Built for heavy duty applications, ND-Series locks are easy to service and maintain, are available with our exclusive Vandlgard® technology, and offer a wide range of styles and finishes to fit your project needs.

 

We don't compromise on security.

The safety and security of your clients’ buildings is something we take very seriously. That’s why every Schlage lock and deadbolt undergoes intensive testing to determine
its ANSI grade level:

• Cycle tests
• Resistance tests
• Door impact tests
• Warped door tests
• Bolt strength tests

We pay attention to these details so you can focus on creating a functional and aesthetically pleasing environment for your clients. In fact, every one of our ND-Series locks meets ANSI Grade 1 standards for safety.

 

Built to perform without fail.

The Schlage ND Series is the toughest cylindrical lock we make. That means you get premium durability and performance in a lock that’s also easy to service and maintain. And because we test our locks beyond the standards required by ANSI, you know that you’re getting a product you can count on to withstand the use and abuse that come with heavy duty commercial applications.
