The ND-Series has long been one of Schlage’s best selling mechanical locks for good reason – it is tough, durable, Grade 1 rated and fits all kinds of applications. Now Now we have made our trusted ND-Series lock even better by making it easier to install. Now we have added these enhancements because we know that a lock installed accurately the first time will last more and perform better and the longer the lock lasts, the lower the price of ownership over the life of the lock. The result: greater peace of mind that each door is protected and secured with a lock built to last.
