Atlo ATLO-KRM-203 is a mechanical combination lock engineered for keyless access to cabinets, lockers and interior doors. The lock operates without electronics or batteries, using a resettable mechanical code to permit entry. Its compact design and tamper-resistant mechanism make it appropriate for securing small storage compartments, utility enclosures, office lockers and similar applications where reliable, maintenance-free code control is required.

Advantages

The mechanical construction provides consistent operation without power or electronic components, reducing maintenance needs and eliminating battery replacement. A resettable combination allows administrators to change access codes as needed without replacing the lock. The compact form factor fits standard cabinet or door mounting points and the robust internal mechanism offers resistance to casual tampering. Installation is straightforward and the absence of electronics improves longevity in varied indoor environments.

Usage recommendations

For reliable performance, install the lock on interior doors or cabinets in dry environments and verify the combination after programming. Keep a secure record of the current code and periodically change it when access control changes are required. If mounting into thin or non-standard panels, ensure proper backing or reinforcement to maintain tamper resistance and secure fastening.
