Continuous Improvements make the ND-Series a Simpler, Smarter, Stronger lock
The ND-Series has long been one of Schlage's best selling mechanical locks for good reason - it's tough, durable, Grade 1 rated and fits a wide variety of applications. Now they have made their trusted ND-Series lock even better by
making it easier to install. They have added these enhancements because they know that a lock installed correctly the first time will last longer and perform better. And the longer the lock lasts, the lower the cost of ownership over
the life of the lock. They have also increased Schlage's warranty to provide 10 years of coverage. The result: greater peace of mind that every door is safe and secured with a lock built to last. So not only do you get their toughest
Grade 1 cylindrical lock, that is ideal for use in schools, hospitals, offices, retail spaces, colleges, universities and other applications.
