Securitron M68 Magnalock — 1,200 lb Bracket-Mount Electromagnetic Lock, Dual Voltage 12/24 VDC

The Securitron M68 Magnalock is a heavy-duty, bracket-mount electromagnetic lock delivering 1,200 pounds of holding force for interior access control applications. Designed for doors where a surface-mount or inline maglock is not feasible, the M68's bracket configuration provides installation flexibility on doors that require an offset geometry between the magnet and the armature strike. Operating on dual voltage — 12 VDC or 24 VDC — the M68 integrates readily into a wide range of access control power supplies and panel configurations. This model is rated for indoor use only and must be paired with appropriate latching hardware and a code-compliant fire-alarm release circuit.

Key Features & Benefits

• 1,200 lb Holding Force: Provides robust electromagnetic retention suitable for high-traffic commercial interior doors, stairwell entries, and secured interior suites.
• Bracket-Mount Design: The offset bracket configuration accommodates doors and frames where direct surface-mounting is impractical, expanding installation flexibility without sacrificing holding strength.
• Dual Voltage Operation (12/24 VDC): Draws 250 mA at 12 VDC or 125 mA at 24 VDC, allowing compatibility with a broad selection of access control power supplies and reducing heat build-up at higher voltage.
• UL 10C Listed: Meets the UL 10C standard for positive-pressure fire testing, supporting use on fire-rated door assemblies when combined with the required latching hardware and fire-alarm release.
• Grade 2 Performance: Rated to ANSI/BHMA Grade 2 standards for commercial-grade durability and reliability.
• Compact Magnet Profile: At 10-1/2 in. × 2 in. × 3-5/8 in., the magnet body fits within typical door header clearances; the armature strike measures 6 in. × 1/2 in. × 2-3/4 in.
• Interior-Optimized Operating Range: Rated for environments from +32 °F to +110 °F, covering standard conditioned commercial and institutional interiors.

Typical Applications

• Interior corridor and stairwell doors in office buildings, healthcare facilities, and educational campuses
• Secured interior suites requiring access control integration
• Fire-rated interior door assemblies (with required latching hardware and fire-alarm release)
• Access-controlled entry points where card readers, keypads, or intercoms are part of the door system

Installation Notes

The Securitron M68 requires latching hardware (such as a latch or concealed vertical rod device) to meet door-hold-open and egress code requirements, and must be connected to a fire-alarm release circuit to ensure fail-safe operation per applicable building and fire codes. Consult the manufacturer's installation guide and your local AHJ (Authority Having Jurisdiction) for specific requirements.
