For over 100 years, Adams Rite has been the Aluminum Hardware Authority, known for their innovative designs and high quality products. When the Maximum Security (MS) Lock? launched in 1955, it quickly became the industry standard and even now remains the dominant locking solution for narrow stile aluminum openings. Today Adams Rite designs, manufactures and markets door and door hardware products to the commercial, industrial and institutional building construction industry and is recognized as one of the leading suppliers in its area of specialization. Our product lines include electromechanical deadlocks and deadlatches, electric strikes and exit devices for exterior and interior doors as well as integrated door assemblies. Our products are designed to complement the clean lines of modern doors, while at the same time meeting safety and access codes.

• Mechanism is similar to the MS1850S Deadlock, but with the bolt size reduced
• This keeps the threshold strike opening to a practical minimum, avoiding collection of debris or snagging on high-heeled shoes
• Armored faceplate protects cylinder set screws from tampering and keeps them from loosening. Not designed for wood door applications
• 360° turn of key or thumbturn projects or retracts the counterbalanced bolt
