Hager 2942 Electromagnetic Magnetic Lock — 1200 lb Holding Force, 12/24VDC, Aluminum Finish

The Hager 2942 is a surface-mount electromagnetic lock (maglock) delivering 1200 lb of holding force with field-selectable 12/24VDC operation. Designed as a failsafe access-control solution, the 2942 is appropriate for perimeter doors, stairwells, vestibules, and other secured openings in commercial, institutional, and government facilities. Because a magnetic lock is energized to lock and de-energizes to release, it is inherently failsafe — the door releases the instant power is removed, making it code-compatible for emergency egress when paired with a proper request-to-exit device and fire-alarm release path.

Institutional Grade Features & Benefits

• 1200 lb Holding Force: Delivers robust magnetic hold for high-security perimeter and interior access-controlled openings.
• Field-Selectable 12/24VDC: A single unit covers the two most common DC power supply voltages; voltage is selected via a wiring-compartment switch, eliminating the need to stock separate models.
• Failsafe by Design: Releases immediately on loss of power — the fundamental egress-safety characteristic of all magnetic locks. There is no fail-secure maglock mode.
• Aluminum (ALM) Finish: Anodized aluminum housing offers a durable, corrosion-resistant profile suitable for interior and sheltered exterior applications.
• Surface-Mount Installation: Mounts directly to the door header; inswing doors require an L/Z bracket set (sold separately — consult compatible bracket options for 1200 lb single-door maglocks).
• Minimal Maintenance: No internal moving parts; periodic cleaning of armature and magnet mating surfaces and a light silicone lubricant application is all that is required to maintain optimal holding force.

Applications

The Hager 2942 is well suited for access-controlled openings where a high holding force and reliable failsafe release are required: office building perimeter doors, school corridor doors, hospital secure-zone entries, government facility access points, and stairwell re-entry doors. For fire-rated door assemblies requiring hold-open functionality, pair a surface closer with a compatible electromagnetic holder rather than using a maglock — maglocks are a locking device, not a hold-open device.
