Product Description
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 we’ve made our trusted ND-Series lock even better by making it easier to install. We’ve added these enhancements because we 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. We’ve also increased our 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 our toughest Grade 1 cylindrical lock, that is ideal for use in schools, hospitals, offices, retail spaces, colleges, universities and other applications.
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.
• Tested to at least 3 times the 1,000,000-cycle ANSI Grade 1 requirement
• Exceeds ANSI A156.2, Series 4000 Grade 1 locked lever torque requirements
• The only cylindrical lock available with our exclusive Vandlgard® technology
Door Handing
All ND levers are reversible. Hand information is necessary to ensure proper cylinder orientation in keyed functions, and finish of latchbolt and strike for locks that are to be installed on reverse bevel doors. Follow the diagram to correctly determine the hand of the door.
Door Reinforcement
Reinforcing unit is required to reinforce and help prevent the collapse of hollow metal doors when locksets are tightly mounted. This kit should be used with long backsets for ND-Series lock installations in hollow metal doors to prevent lateral movement of the latchbolt. Specify door thickness, 1 3/8” (35 mm) or 1 3/4” (44 mm), when ordering reinforcement kits.
Latches
ND-Series latches are adjustable for flat or beveled edge doors. Latches and strikes are furnished in brass, bronze, or chrome finishes to be compatible with lock trim. When ordering, specify quantity, part number, and finish. All ND-Series latches have 1/2” throw and 1” housings except 2 3/8” backset latches, which includes sleeve G506-815 to fill a 1˝ edge bore.
Long Backsets
ND-Series locks with 5˝ backsets are normally furnished with 1 1/8” faceplates and 1˝ housings. Links installed in metal doors require one A501-567 sleeve and 43-005 (order separately) to join latch and link.
Strikes
All Schlage strikes are furnished complete with screws. The standard ND-Series strike has a 1 3/16” lip. When ordering separately specify quantity, product number, finish, and lip length.
