Rack door lock Rittal 8618.304 — zinc housing, replacement lock for server cabinets

Rittal 8618.304 is a replacement rack door lock designed for server and network cabinets. The lock features a zinc housing and zinc finish, supplied as a single unit weighing approximately 20 g. It is intended as a direct replacement locking element that fits standard Rittal mounting arrangements to secure cabinet doors and panels.

Advantages

This replacement lock offers a compact, lightweight design with corrosion-resistant zinc construction suitable for indoor rack environments. As a single-unit spare part, it simplifies maintenance and reduces cabinet downtime by providing a ready-to-install locking element compatible with Rittal-style door fittings. The neutral metallic finish integrates discreetly with most cabinet interiors and exteriors.

Suitable for

• Replacement of worn or damaged door locks in server and network cabinets
• Use as a spare locking element kept in maintenance kits
• Small-scale cabinet retrofit projects that use Rittal-compatible mounting
• Securing access panels in IT racks and telecom enclosures

When it may not be suitable

This zinc-housed replacement lock is intended for rack and cabinet doors that accept Rittal-style locking inserts; it may not be compatible with non-Rittal or proprietary locking systems without matching mounting geometry. It is not a high-security or electronic access control device and should not be used where advanced tamper-resistance or audit logging is required.

Key specifications

• Housing material: zinc
• Finish: zinc-plated / zinc-colored
• Supply: single unit (1 pc)
• Weight: approximately 20 g
• Compatibility: designed for Rittal-style cabinet door mounting

How to use

To install, remove the existing locking insert from the cabinet door according to the cabinet manufacturer's instructions and insert the Rittal replacement lock into the mounting aperture until it seats. Secure any retaining screws or clips as required by the door assembly. Verify correct operation by turning the lock with the appropriate actuator or screwdriver type specified for the lock design, and confirm the door latches and unlocks smoothly.

What to consider before purchase

• Verify that the cabinet door accepts Rittal-compatible locking inserts and that mounting geometry matches.
• Confirm whether a keyed or interchangeable lock type is required for your access control scheme (this unit is a mechanical replacement locking element).
• Ensure the finish and material meet your environment's corrosion-resistance needs.

Usage recommendations

Keep a spare unit in maintenance kits for quick replacement during rack servicing. For installations requiring higher security or electronic access control, consider combining this mechanical lock with additional access control measures or selecting a dedicated security lock system.
