Schlage Electronics M420 Single Magnetic Lock

Product Description

The SCHLAGE ELECTRONICS M420 is a single magnetic lock with integrated traffic control designed for access control applications in commercial, institutional, and multi-family buildings. Magnetic locks use electromagnetic force to secure a door, releasing only when power is interrupted or an authorized credential is presented. The M420 measures 10.3 inches in length, 3.8 inches in width, and 2.8 inches in height, making it suitable for standard door frames where a low-profile form factor is required. Installation is performed by licensed access control or low-voltage security technicians.

The M420 is applied in commercial and institutional door openings where traffic control and electromagnetic locking are needed at a single door leaf. Typical installations include office entryways, stairwell doors, server room access points, and controlled corridors in multi-family or institutional facilities. The unit ships as a single-quantity item and is suited for new construction or retrofit access control projects where a compact magnetic lock is specified.
