Schlage ND Series Grade 1 Cylindrical Locks

Overview

The Schlage ND Series offers a comprehensive range of solutions designed for beauty, function, and enduring quality. This series provides a common aesthetic and consistent user experience across mechanical, electrified, and electronic lock options, catering to diverse market needs including K-12 and healthcare.

Founded on Walter Schlage's invention of the cylindrical lock over a century ago, Schlage, a part of the Allegion family, continues to innovate in security hardware and access control. The company emphasizes quality, customer trust, and comprehensive support, including architectural consulting, technical services, and code compliance training.

The ND Series locks significantly exceed BHMA Grade 1 requirements for cycle, lever torque, hammer blow, and lever pull, ensuring durability and reliable operation even under demanding conditions.
