Dynalock 3000-TJ30 Electromagnetic Lock For Single Inswinging Doors, 1500 Lb.

The DynaLock 3000-TJ30 is a full-size 1500 lb holding force electromagnetic lock configured with the TJ30 top jamb bracket for a single inswinging door. The 3000 series is DynaLock's heavy-duty maglock, built for life safety and high security on rated or nonrated doors and frames. The TJ30 top jamb configuration is what makes this version right for an inswing opening, mounting the lock to the face of the frame header so the door secures correctly as it swings inward.

Why the TJ30 Top Jamb Configuration Matters

This is the detail that trips up most maglock orders. A standard DynaLock 3000 mounts for a single outswinging door. The TJ30 is the top jamb bracket kit that converts a 3000 into a 3000-TJ30 for a single inswinging door. Same 1500 lb magnet, different mounting geometry for the opposite swing. If your door swings inward, this is the configuration you need. If it swings outward, you want the standard 3000 instead. Confirming door swing before ordering is the single best way to avoid getting a maglock you cannot mount correctly.

How the DynaLock 3000 Maglock Works

An electromagnetic lock has no latch, bolt, or moving parts. Power runs to the coil, the coil magnetizes, and the armature plate on the door bonds to the lock face under 1500 lb of holding force. Cut power and the door releases instantly, which is why maglocks are specified for life safety and fail-safe egress applications where the door must unlock on a fire alarm or power loss. The 3000 series delivers the full 1500 lb rating, putting it at the top of DynaLock's single-door holding force range for openings where maximum security matters.

Because the lock releases the moment power drops, a maglock installation must coordinate with the building's access control, egress, and fire alarm systems. Plan the request-to-exit device, power supply, and release method as part of the same job, not as an afterthought.
