Complete Guide to Electromagnetic (EM) Locks for Office Glass Doors

Modern corporate offices in Hyderabad feature sleek, frameless glass doors. However, securing glass entrances requires specialized hardware because conventional mechanical mortise locks cannot be bolted through tempered glass without risking structural shattering.

Why 600 lbs Electromagnetic Locks Are the Industry Standard

A standard single-door EM lock produces 600 lbs (280 kg) of linear holding force. When powered by 12V DC, the magnetic field locks the steel armature plate against the electromagnet with force exceeding the physical push capability of multiple adults.

Frameless Glass Door Mounting with U-Brackets

To mount an EM lock on a 10 mm or 12 mm frameless glass door, a precision aluminum U-Bracket is utilized. The U-bracket slips over the top edge of the glass pane, secured by high-tensile set screws and rubber cushioning shims. The steel armature plate is then affixed to the U-bracket, eliminating the need to drill into the glass.

Life Safety and Fire Escape Compliance

Electromagnetic locks are strictly Fail-Safe devices: they require continuous electrical power to stay locked. In the event of a power cut or building fire alarm activation, the circuit breaks automatically, releasing the magnetic grip and ensuring occupants can evacuate safely without delay.
