Lockey MC728B Mechanical Combination Cam Lock

Product Description

The LOCKEY MC728B is a mechanical combination cam lock finished in black, designed for keyless access control on doors, cabinets, enclosures, and similar applications. This lock operates without batteries or electronics, using a mechanical push-button combination mechanism to control a rotating cam. It is suited for commercial and light industrial environments where reliable, low-maintenance access restriction is required. Licensed locksmiths, security installers, and facilities maintenance professionals are the primary installers. The black finish provides corrosion resistance and a clean appearance on metal or composite surfaces. The unit ships individually and measures 3.3 inches in length, 3 inches in width, and 2.4 inches in height.

The MC728B is used in applications where a keyed lock is impractical or where keyless entry improves workflow. Typical installation scenarios include utility cabinets, electrical enclosures, storage lockers, gate latching mechanisms, and panel doors in commercial or light industrial settings. Its mechanical operation makes it appropriate for indoor and sheltered outdoor locations where electronic locks would require additional weatherproofing or power infrastructure.

Installation Notes

Installation is typically performed by a licensed locksmith or qualified facilities technician. Before installation, confirm the panel or door cutout dimensions match the lock body to avoid rework. Standard cam lock installation tools apply, including a drill or hole saw and appropriate fasteners for the panel material. Verify that the mounting surface thickness is compatible with the lock body depth before final assembly.
