Lockey MS40 Mechanical Combination Slide Bolt Lock

Product Description

The LOCKEY MS40 is a mechanical combination slide bolt lock finished in black, designed for keyless access control on doors and gates. It operates without batteries or electronics, using a mechanical push-button combination mechanism to throw or retract the bolt. At 5.6 inches long, 2.3 inches wide, and 1.6 inches tall, this compact unit fits a range of door and gate mounting applications. Installers in commercial, industrial, and residential settings rely on this type of hardware where electronic access control is impractical or unnecessary. The black finish suits both interior and exterior applications where a low-profile appearance is preferred.

The MS40 is suited for single doors, double doors, and gate installations where a keyless, battery-free locking solution is required. Typical installations include pool gates, utility enclosures, storage areas, and restricted-access corridors. The push-button slide bolt design allows authorized personnel to operate the lock without carrying a key, making it practical for shared-access environments in light commercial and residential settings.

Installation Notes

Verify door thickness and frame clearance before installation to ensure proper bolt travel and engagement. Consult local building and fire codes, particularly for egress doors, before installing any locking hardware.
